4 from 5 Sounds amazing!

The kit was a lot of work but in the end it sounds amazing. I love the distortion on Rythm channel and the brightness switch brings my les paul much needed clarify. Clean and Lead channel have a slight volume difference and the eq of each channel needs a slight adjustement to have more effect.

The only downside is that the documents are a bit unclear. Then again this is not meant for first time builders and if you have built mant amps then this is not a problem.

5 from 5 Great sound, great kit

About 30 hours of work. Its not easy, documentation is hard to found and isnt complete (boost switch of Lead channel is not in the schematics from Andys website, you can copy it from other amplifiers like N5X:, but if you have some experience you can do it. Easily you can build Presence control and boost switch on all channels.

Enclosure may be better, its poorly vented, and drilled option is not available. Some jacks looks cheaper, but works correctly.

It sounds good, Clean channel is rich and clear. Rhythm and Lead channels sounds from smooth distortion to high gain distortion, from blues to metal.
