New Amp: Mesa Mark IV

A while back, I listed my Marshall TSL for sale online. At the time, I was enjoying the 6100LM more and figured it made sense to sell it off if I wasn’t using it. Thanks to a number of interested and chatty folks I met on Reverb, I learned some new settings and grew to love the amp again, so I took the sale down. However, one person was interested in a trade for a Mark IV combo amp - which didn’t go through as he was able to sell it for cash first. While researching the trade, I started to really like the Mark IV tones and thought it would be great to have especially since it would be so different from my mostly Marshall-like collection so far.

Fast forward a few months and I found a Mark IV Medium head for a really great deal and picked it up. I specifically wanted the Medium head so that the “lead voicing” switch was on the front panel. I’m really a tweaker at heart and though I would use that switch with enough frequency plus the medium head is a better platform in case I had to place another head on top.

This is a killer amp - the high gain tones are super tight and articulate, and even sounds great boosted. Throwing a light chorus and reverb in the loop can get tones very close to Whitesnake’s 1987 album tones (even though they used a Mark III), and of course it can nail those modern metal tones such as Lamb of God.

Dialing this amp is a steep learning curve, and I understand now why players come back with such conflicting reviews on the Mark series amps. Their EQ is situated much earlier in the circuit, right after the input gain stage. This is very different to the usual Marshall style post-EQ that most high gain amps employ. On the Mark, you really need to bring up the treble control to maximum, keep the bass low to avoid flubbiness, and use the graphic EQ to shape the sound you want in the room. The idea of maxing out the treble control on a Marshall style amp is totally alien, but it sounds fantastic with this style of circuit.

Caps in this unit date to 1997, and it came equipped with 2x 6L6GC and 2x EL34’s, which sound great to me.

New Amp: Marshall 6100LM... again

I was so thrilled with my 6100LM that I spotted another one for a very low price on Guitar Center’s used lisings, so I pulled the trigger. I figured I could keep whichever one I liked better and sell the other and pocket a few bucks along the way. This unit dates from 1995 and has the same 5881 power tubes as my 1997 model.

Turns out, this one has been modified - and poorly. Channel 1 and 2 feel about the same, but channel 3, the most exciting part of the 6100LM to me, has far less gain and less fullness. Looking inside, there is some shoddy soldering on the lead PCB and I didn’t take the time to investigate further as I’m able to return this amp for 45 days no questions asked.

New Amp: Marshall 6100LM

Finally added another Marshall to the collection! This time another 3 channel one, and from around the same era as my TSL. This one dates from 1997, very late in the production run of these 6100LM’s and is equipped with 5881 power tubes.

I’m very happy with this amp and it barely steps on the toes of my TSL. It does cover some of the same ground, but the tones of this model are definitely more classic sounding than the TSL, especially the crunch channel, though it sadly lacks the TSL’s great spring reverb.

The most exciting part of this amp for me is the “LM” lead channel - I thought the TSL had a good amount of gain but really felt best boosted with the gain rolled down. This 6100LM needs no boost to achieve the same level of gain - especially with the mid boost switch pressed in. Channel 2 is also capable of a similarly massive amount of gain with both switches in (Mode C), though it lacks the mid boost ability. Also usable on channel 3 is a “contour” switch, which shifts the mid frequencies and scoops some of it out. While I don’t usually use the contour switch, my first impression is that with that switch in and the gain turned up can get very brown sounding, and could probably do a great impression of the Unchained riff.

New Amp: VHT Pittbull 50/CL

I picked this up really on a whim. Usually I research for months/hours of clips, forums, reviews etc, but I only knew that this was a popular amp for metal styles and a few minutes I spent playing a VHT Pittbull 50/ST in a guitar center about 5 years ago.

Well I am sure glad I did, because this is a fantastic amplifier. Somewhat unique to Pittbulls, this one is optioned with tube powered spring reverb, and no graphic EQ. I’m sure the graphic EQ is great to have, but I love the ambience the reverb adds with its relatively short tail, and I can always add an EQ to the FX loop later. Also a very cool feature is the switchable 5U4 tube rectifier, which can be set to both channels, or none, or only on Red but not Green (my preferred setting).

Both channels can be set exactly the same, which I really like as I can dial in two high gain tones, or two crunch tones, or clean/high gain or anything in between.

New Amp: Splawn Quickrod (2008)

Since the Laney AOR didn’t quite scratch the JCM800 itch, I went on the hunt again. A local vintage music shop had been posting listings on craigslist, but the owner does not ship. I saw a JCM800 2204 in some photos, so I took a day and drove down to see what was in the shop.

This shop is Jimmy’s Vintage Music of Auburndale FL, a beautiful small town roughly halfway in between Orlando and Tampa. It was no let down - vintage Fenders, Marshalls, and all manner of beautiful guitars were on display.

After trying out the JCM800 2204 and feeling that the master volume was just too difficult to control, the knobs very easy to rotate and slightly scratchy at the lowest settings due to age made it hard to imagine taking it home to my studio. The owner suggested I try the white Splawn, complete with a road case and matching white 4x12 Splawn cab.

I was immediately thrilled by the sound - it wasn’t overly gainy, but it was much thicker, fuller, and more in line with the modded Marshall tones I wanted out of this type of amp while keeping its vintage Character. After some quick negotiating, I took the head home sans cab and road case. The cab was fantastic - no argument - but I just couldn’t justify the space at home.

New Amp: Laney AOR 50 Series II

While I love my current amps, I’ve been on the lookout for something a little more classic sounding. I’ve read that Warren Dimartini of Ratt, one of my favorite guitarists, used Laneys on stage in the 80s and heard these AOR models compared to the JCM800s of the time.

However, these are priced far lower than any JCM800 I’ve seen, this one I picked up for only $350 on Reverb! (This is my first Reverb purchase as well).

My first impressions are that it is no JCM800 clone, or at the very least the circuit is different enough that it isn’t a replacement for one. The AOR channel has quite a bit more gain on tap, and the regular channel is much darker than any 2203/2204 I’ve played. There are several “pull” knobs that add in boosts in the EQ, so it’s definitely more versatile than a stock JCM800 type amp.

So far, my favorite setup is using the “AOR” channel with the bright engaged, but the normal channel without. I can dial in a decent dirty clean without being ear piercing, then footswitch to the AOR channel for a huge gain boost as well as cutting through better with the additional highs the bright switch adds.

New Amp: Laney Linebacker 100R

Happened across this one in my local GC super cheap. After some quick googling, I found these came with a few variations of nice vintage Celestion speakers… the salesperson wouldn’t let me open it in the store (closed back) so I bought it, took it out to my car and opened it up in my trunk instead.

I was pleased to find an ‘88 Celestion G12H-100 speaker - I knew it would be nice but I didn’t expect it to be as good as it is - one of my favorite speakers so far!

New Amp: Jet City JCA2212C

Back when I was searching for my first tube amp, I settled on a Marshall TSL. However, near the top of my list was the Soldano Avenger, or Hot Rod 50, which could be found in the low $1000 range at the time. I never got my hands on a real Soldano, but with the Jet City amps out using very similar circuit designs it’s hard to argue with them for the price.

While browsing the MusiciansFriend website, I found an open box JCA2212 combo amp in “fair” condition for a very low price - $193. It arrived with some large dents on the top panel, but otherwise it’s in good condition and the amp sounds perfectly fine.

The stock Eminence speaker is close to the Legend series, though I’m not wowed by it. I plan to purchase a Celestion Creamback speaker instead and see how that sounds instead.

These Jet City amps are also popular modding platforms, since they have relatively simple circuit designs and the Soldano circuits are easily reversed so in theory, you could modify a Jet City amp to be nearly identical to a real Soldano amp.

I planned out and purchased a number of different caps and resistor values to try in different areas of the circuit. Initially, I installed 5x 3-way mini switches, but settled instead of some larger 2-way switches with component values that made a more noticeable change. This was my first experience with modifying amps and I had a blast and learned a lot. Looking forward to tinkering with some other amps in the future!

New Amp: EVH 5150 III 50w Head

I came across this one at my local Sam Ash music store. The amount of gain and how thick and full it sounded really surprised me so I worked out a deal and took it home.

It’s a great compliment to my Marshall TSL, which has a dryer tone with more upper mids and less bass. The EVH can be dialed in conservatively for classic rock tones but the fun to me is going all out on the red channel, which is as saturated as the 5150/6505 it is based on but with more hollow sounding mids and more complexity, making it sound a little more clear and articulate.

New Amp: ADA MP-1

I’ve heard great things about these and spotted one at the same Musicgoround I purchased the TSL head from. While staying over at a friend’s place in Atlanta one weekend, I went and picked this up. It has some really killer tones, and I’ve been playing it run into the FX return of my TSL head. Dialing in tones is a little tedious but they can be saved to any of 128 user presets, and can be recalled with a few taps of the front panel arrows or with a MIDI footswitch.

This is definitely more classic sounding than my TSL, and a lot darker. My only complaint is it is also noisier, especially at high gain settings.

(This is the earliest picture I can find of it)
