Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

Hello,

I currently own 3 2101's and I want to start to experiment with 
different tubes.  I understand which distortions V1 and V2 coordinate 
with but I would like to try some different value tubes.  But before I 
do I wanted to check with the memebers here.

Will the 2101 accept a 12AT7, 12AY7 or possibly a 6201 without damaging 
it?

With that said...  what is the current mindset with replacing the 
12AX7s with NOS 12AX7s?

Thank you.

Thanks,

Once I realized there was a "search" function here I've been reading 
the other posts regarding this subject.

Go to eurotubes.com  they can set you up with the best warm sounding 
tubes made today. Also can suggest values in which will sound best for 
your style of music or sound.  Personally like the high gain JJ's. Good 
Luck!

Thanks everyone!

I do have more than a handfull of 12AX7's, 12AT7's, 12AY7's and some 
6201's.   Some are vintage, some are new and some are NOS.  I've been 
switching various tubes in and out all day and I'm still not sure which 
way I'm going to go.

I guess I should have given everyone a bit more background on my 
playing style but it would suffice to say I use my 2101 for everything 
from Jazz to Country and everything in between.  I love these things.

Again, thanks for all the help.  I'm sure I'll have some more questions 
as time goes by.

The following is an excerpt from an email that I sent to a customer - I 
was too lazy to type it all out but it briefly summarizes info about 
tubes


Tubes -- the tube tones vary mostly depending on their source. Chinese 
tubes are the cheapest and have the highest gain but they have the 
glassiest, solid-state like tone. They are also pretty inconsistent if 
you buy the non branded ShuGuang-made tubes. The standard 2101 has 
Chinese made tubes that are "matched" by Penta (in California). Russian 
tubes have almost as high a gain as the Chinese tubes but have a 
warmer, more tube like character. All the Russian tubes come from the 
same source -- Sovtek -- and they are then re-badged by companies like 
Mesa/Boogie, GT, Electro Harmonix, etc. I personally use British or 
Japanese Mullard/Panasonic tubes in my preamps. They have slightly 
lower gain but give the best/warmest overall tone in my opinion, and 
are usually very consistent across the board. The older marshall amps 
are usually equipped with Mullard tubes but the tubes are significantly 
more expensive.

The russian tubes are a good compromise between gain and tone. There 
are construction diferences in the tubes. the GT tubes are usually 
"long plate" tubes. This makes them a little more susceptible to 
microphonics the newer "short plate" Mesa/Boogie tubes. What happens is 
that when playing loud, the vibration transfers into the processor and 
tubes and cause the plates to resonate and vibrate along, causing a 
feedback like tone. This becomes a problem especially for musicians 
unfamiliar with their tube preamps and leaving them sitting on the 
combo amps or speakers.

Hope this helps

I always keep my tubes away from my speakers. Hard to get away from the subs vibrations though. I have the GT s in mine and they work nicely for me. ... From:

I dont care for Ruby's , Penta's, or GT's. I do like Sovtek and I love JJ's.
