I've always been able to use the master volume on my JMP50 master volume and get good tone at bedroom levels. In my new flat it's a little too loud though, so I've been eyeing up some of these popular lower wattage amps. I am just on the way back from Guitar Guitar in Epsom where I tried a bunch. I was after the same NWOBHM tone as my Marshall.
Honestly, 15w is barely quieter than the 50 of my JMP. For bedroom recording usage, I reckon 1w is the way to go. Here are my thoughts:
Orange Tiny Terror: it's the classic and still sounds decent. But I see no reason to pick it these days considering the other options available. Still dislike the 7w mode.
Egnater Tweaker: more versatile than the Orange, sounds a bit better, yet more or less the same price. Clearly it's the midprice option to go for at 15w. For me it's still too loud and furthermore the Marshall setting is a bit too modern for my taste. It is dynamic and hifi though.
Laney Cub Head: less dynamic and defined than the Orange or Egnater. But it sounds pretty good anyway (just a touch boxy) and also has reverb and a 1w option. At 200quid you can't go wrong really. New valves might help(?).
Vox Nighttrain: liked it. Very Voxish though, not my tone. Both pentode and triode mode sounded good.
Vox lil Nighttrain: sounded poor next to the bigger model. Less life to it.
Marshall Class 5: no master volume and far too loud. Would need mods. Basic tone good.
Marshall 1w JVM: far too much gain
Marshall 1w JCM2000: quite nice actually. It's got an FX loop and good volume range. The shared EQ didn't work very well though, I just left it on the gain channel. For me it lacked a bit of character, but it was a well thought out design.
Marshall 1w JMP: it's got 'the tone' sounded *great* actually. I miss a master volume though and the EQ was rather subtle. Gets all the emotion points though.
So as you can probably guess, I saved my money. I'd like to try the 1w JCM800 though.
Frankly only really the 1w JCM sounded as good as my existing Marshall. The rest were less good. The Laney is tempting at the price, and the Egnater blew the Orange away, but too loud for me probably.
So I stick with my JMP50 for now ;)
