Thanks for the responses! I was thinking it was the lytics... Do you guys think adding a seperate bypass cap and resistor for the shared v1 v2 one would be a nice improvement for these fender amps? I could fit one easily with some perfboard or something. and I am modding my normal channel to have reverb and have a different voicing- so I could try something like a .68uf with a 2.7k resistor. worth doing? Also i'm still thinking the .001 coupling cap near the PI could be increased with favorable results (to me)- maybe even just like .0022uf (would that even make a difference in sound)- what do you guys think? I feel like I've read thats a common mod...
also wondering if a mid range control would help me get closer to jerry's mid range response? Or is the stock 6.8k resistor pretty much there?
What about a presence control or having a switchable NFB?
I was also checking out weber's kits- and they have a kit for adding a tube buffered fx loop that has an adjustable send and return (optional)- the send can be used as a preamp out without disrupting the flow of the amp apparently? With that I could have more control over my preamp vs power amp clipping. and I really dig using a reverb pedal (actually looking for a new one- kinda going between alesis nanoverb or another version- and the tc electronics hall of fame PGS edition- which has some amazing cathedral reverbs)
Anyone have any tube recommendations? I just sold 4 tung sol 12ax7's- absolutely hated em- too much gain. I have been digging this old westinghouse 12at7 in v2 and an Ei in v3. smooths everything out- i get more chime, doesnt overdo the pick attack. Get more power amp fire cuz I can turn the amp up louder. along with a 12ax7 in my phase inverter its been a good combo- but the 12at7's have begun to get microphonic (i feel like microphonic tubes haunt me- i've always had major problems with microphonic preamp tubes) I've tried EHX, JJ, mullard (which i loved the sound of, but they went microphonic way too quickly), Ei, westinghouse, sovtek 12ax7's. I've heard the "fender" brand tube is actually a relabeled 5751- maybe thats the ticket? Anyone have recommendations? I'm not set on 12at7 in v1 and 12ax7 phase inverter- I'm thinking 5751's in both spots might be the ticket.
I really need a 6L6 recommendation- I'm leaning towards these TAD (tube amp doctor) tubes that are supposed to be like old RCA black plates- or these tung sol's that supposedly can handle very high plate voltage, which could be good with the SS rectifier.
Speakers- I've read on this forum that steve kimock thinks a single speaker with 2 tubes is the best combination. I was thinking about using one weber california (i got to compare a california with a neomag and a k120) I didnt like the neomag and actually liked the california better- it was warmer and fatter sounding- probably doesnt cut through like the k... But hey instead of spending $450 on a pair of k's I could get a single 4 ohm cali for $105. I'd like to cut down the weight of my amp by using a single speaker, but will I lose a bunch of spread and perceived volume going from 2x12 to a single? Does it really matter that much in an open back cab? I was thinking a weber beam blocker would help me with soread- yeh? Also the cali's are rated at 80 watts... my pro at 40, so I was thinking using one speaker might have another advantage in taht I'll be able to drive the speaker harder and closer to its sweet spot. whatdya think
As always thank you for the help! Always greatly appreciated... Recommendations, opinions, off topic rants, long winded desciptions, short statements of truth and fleeting moments of brilliance are all accepted with gratitude and are highly valued! Thanks!
--Thanks for the carbon film recommendation- However, I've actually considered changing the plate resistors to these Takman brand carbon films... they arent too expensive, but they aint cheap- they sound fantastic, very warm. I'll check those KOA's out too though. Check out those takman's though if you ever need some low noise great sounding carbon films
