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

hi Guys I have an 2101 Artist from 1994 it workin very very well the 
distotion clean tube and grunge sound great but, the saturated and the 
distorted tube and heavy sustain sound unclear, not really useable when 
playin more than one tone. Any suggestions what is wrong or what can I 
try to make these distortions sound better?

You could try 2 things...

1.  If they are the original tubes you may want to swap them out.

2.  Play around with the EQ a bit.  The sound might be there but need a 
little push in a couple of the frequencies.

Ok thanx, I have changed the tubes and now I'm playin with the EQ it's 
getting better but I'm not satisfied yet maybe I have to get used to a 
new sound ?? let's see how far I get in about one week.

Ok I did put in new tubes electro harmonics 12 AT7 or is it really 
importand to use a special brand of tubes ??that give a brighter 
distortion it helps now I'm tryin to get gain 1 and gain 2 right and 
the EQ I hope to get it right in a couple of days thanx

The input gain to the tube circuit can be increased. In fact, earlier 
2101's were factory set to a lower input gain and can be adjusted to 
the updated level using the Clean Tube Setup on this page:

My schematic identifies the trimpot as P9 instead of R188 though, so 
look for either on the board.

As far as the EQ goes you may also want to adjust the universal EQ for 
the whole unit in order to match your setup.

good luck,

blues rock sound by playin with the EQ with plenty of sustain and also 
clear as I wanted it but only with the bridge pick up of my 
stratocaster with the next pick up it becomes unclear but I think I can 
adjust that with EQ but I will look for the trimpot and try and see 
what happens thanx again for your help (everybody who helped me)
