Well, this is now the 4th JCM900 Mk III I’ve purchased. I know that’s excessive, but I really love these amps - I’m just finding it difficult to find one in good condition for a reasonable price. I’ve had two other heads, both in extremely rough condition - just like this one is, aesthetically. I remember returning those heads before, as they both had internal issues as well (loose tube sockets, burned out traces on the PCB, etc). This latest addition is pretty ugly - but functionally it is in much better shape than those two so I’ll likely be keeping this one.
As expected, it sounds fantastic. I did a lot of A/Bing between this amp and my 2501 combo (same preamp circuit) and they sound extremely similar, and that’s exactly what I wanted. While I love that combo, my new studio is really built around shelving designed for heads and that’s what I’d prefer to have, so I’m looking to get rid of my combo amps, at least any combo amp that has an equivalent head version.
