custom vibrolux reverb moyer mods altering sound

Post by bieworm »

Did all the moyer mods and the amp is really clean up to 8 on the volume dials.
Also added a switch on the nfb loop to switch back to cvr mode..but..when in cvr mode it breaks up around 5.5 instead of 3.5. I realise that the spread on the volume dial has another character but anyway it does not sound cvr-like in overdrive anymore.
my guess it has something to do with the change of resistor value at R41? Or maybe the biggest change happens in the preamp where R23 went from 47k to 82k ? I wonder what I can do here...make another switch where I bypass the wire from V1 to pos 6 which then must run through a R23 of 47k ?
Any ideas my friends ?

I could may be point Ya in the right direction if you posted a schemstic for those of us who are not familar with those mods you put in!

I would do the NFB/PI tail switch like this. How did you do it?

Put it back to stock as God and Leo intended and then you won't have to worry why the mod isn't working :)

I won't worry for now...went playing with the band yesterday and the cvr is just perfect now. I couldn't hear it at home but when playing loud with other musicians It's just super sounding. On the VVRI mode It's nice clean and sparkling..in cvr mode it is right on the verge of drive..very responsive on string attack. That is for the bright channel.
the normal channel is on the same volume spot sweet sweet overdrivin'..gotta buy me that a-b pedal and use only the amp with a booster. The boost on my fulldrive 2 is just perfect for that performance :lol:
this is a pic before the switch was planted in..the switch sits in between the tip and the wire now and is situated above v1 (see original post pic )
