Thinking about picking this up......for a starting point on the "tone".....is this a good amp as is or do any mods need to be done to it? Possibly put a JBL K120 instead of its current 12". Obviously this is before any pedals or effects are added.
I would have never guessed a 5751 in V2 would do that. I always assumed that a 5751 is the same as a 12AX7 which increases gain and lowers headroom. I use either 12AY7 or 12AT7 in V1-V2 and it really cleans it up great. Also if only using the reverb channel I just remove V1 altogether so the signal does not split between V1 and V2.Grateful.Ed wrote:3. You can get more headroom with a 5751 in V2.
Absolutely try a 12AY7 in V2. Actually, if you don't use the normal channel at all, remove V1 and you will get a slight boost as well. Easy mod worth trying. Allows the dial to be turned up even more before breakup with the AY7. The sound however will depend on the tube. I like EH for the expense and easy availability at local stores. I have used RCAs in that spot and they sound great but got microphonic quickly.Grateful.Ed wrote:The 5751 is about 70% the gain of 12ax7.....you're going to even lower gain with the 12ay7 (45%) and 12at7's (60%)....I've never tried those, but now I'm tempted.
