For starters it was a bv6212.... I removed the speakers and cut down the cab to make it into a head which i run to a closed back 2x12 cab i built which currently has line6 speakers( I will be upgrading my speakers to a v30 and a greenback as soon as i have the money) as for the amp i just replaced all the tubes, jj's for the 4 12ax7's and gt's for the 2 6l6's as well as a gt 12au7. Also I modified the tone stack with a .1uf cap on the low and .022uf for mid on the distorted channel.... that mod definitely improved the sound and tonal flexibility imo, kinda goin for a mesa mark3/single rec sound. Any ideas on how to make it sound less muddy and what compnent(s) i need to change to alter the character of the distortion?
Guitar amplifier posts belong in Instruments And Amps, please see the forum subheaders.Thanks for the help guess I'll just go with trial and error.... and thanks to the condescending moderator for being unnecessarily rude, because its my fault your forum makes no logical sense where tube amps aren't under the tube section....... deuces.
I am unable to see rudeness by the moderator.
In his notice of moving your posting (for your benefit), I read the word "please" and there is a smile face too.
My on-line participation includes many forums, that I often read and enjoy besides periodically weighing in, on a posted topic here.
My understanding of the separation of musical instrumentation amps away from "Tubes/Valves" permits a more focused group of contributors, who tend to lean that direction.
Moderators have a significant and often difficult job in their duties on any given on-line forum. Personally, I appreciate what a moderator does daily.
Anyone who declines the massive knowledge and experience available in well moderated forums is walking away from a wonderful opportunity.
For quite a few years, I was an authorized service tech for St Louis Music which was acquired by Loud Technologies. I would have been interested in seeing a variety of others chime in with questions, hints, and possible modifications, since I am very familiar with Crate plus many other models and brands in instrument amplification.
I no longer perform a lot of customer bench work, mostly because after doing electronic service since starting at age 12, the elapsed 40 years brings me to now choose to do select jobs and not spend so much time on the bench.
If you do reconsider participation on the forum, there is a wealth of input to be read, from around the world.

Playback systems even though using tubes are designed completely different, it only makes sense to keep them separate to avoid confusion.

As a practical matter, this web site is primarily a hifi place, and the guitar amp section is a side niche. The needs and goals of guitar amps are remote from the needs of the hifi community.
I suspect the OP may have left, but if not...
THE single most effective way to change the sound of an amp is to change the speakers. If you plan to install different ones, you might wait til then to make any more tonal mods.
Just an opinion, but while you like the increased capacitance in your tone stack, it does tend to push the emphasis down to lower freqs, and that might be part of your muddy.
Go over to duncanamps.com and look up his Tone Stack Calculator - the TSC - it is a free bit of software that will show the response of several common tone stack circuits and let you adjujst controls and see in real time the response change. It also allows yo0u to change the component values and see those changes.
As to distortion, there is tone shaping throughout that channel, many places to fiddle with it.
