Epiphone Valve junior

bulldogguitars · 12-21-2006, 03:42 PM

I just bought two of these little guys, and I gotta say they sound pretty darn good. But..... was wondering what I could do to clean one up. Meaning, have no breakup at a cranked level.

Rip the guts out and replace them with the guts of a UL Twin?

Seriously, how are you going to get a big clean sound with only 3 watts available? I think about all you could do is reduce coupling capacitors to cut the bass and give the illusion of more power.

I knew my options were limited. Ive started replacing the caps already and replaced the 12ax7 with a 12au7. Its better, and I can live with it now. Thanks

Do you really think a Twin would fit in there? Might be a little cramped. Perhaps if we left out the reverb, that should be a space saver.

If you go over to 18watt.com there is a very long thread about the VJ. It seems to be a favourite topic there. The thread is months old and has over 2K of posts. I can't be bothered since I wasn't there at the beginning and have never heard or seen one of these amps. There go your holidays.

Did the 12AU7 really make any difference? I may want to try this!

tubeswell · 12-30-2008, 02:56 AM

Any lower gain pre-amp valve will clean up the signal going into the output tube (but then there goes your typical champy sound)

TD_Madden · 12-30-2008, 03:08 AM

changing preamp tubes are cheap and easy "mods".

I put a 5751 tube in mine. Now I get some overdrive with it cranked. Clean otherwise.

Rayme · 01-05-2009, 12:45 PM

Thanks for the info Ronh, looks like a cheap way for me to play with the sound!
