I'm bored. That's it. That's pretty much the premise for me looking at amp kits. I have built a 5E3 kit in the past (Mission) and several pedal kits. I've already got a total of 4 amps (PRRI, 5E3, 57 Twin, and 5F6A) so there aren't really any gaps in my lineup. The one that has my attention is the Mojotone 6G16 Vibroverb. I used to own a CVR and it was a great amp. I love spring reverb and tube driven tremolo and 210 speaker setups. Downside? These ain't cheap. So, do I do it? Or just forget about it and go play the gear I have?
