Okay thanx for all replys. Atm I have Peavey Delta Blues 115 Tweed combo but I could not get channel switch to work via Helix with this amp. Hence I'm considering to get Marshall dsl20 cr. So, I assume this item from Helix manual concerns Peavey, at least my Peavey: "The Helix device's ability to control external amp channel and/or reverb switching has been tested with many popular amps and heads. Unfortunately this does not guarantee compatibility with all products. Note that, depending on the circuitry of the channel switching jack in the guitar amp used, the EXT Amp function may not operate as expected."

Okay thank you rd2rk :) I appreciate your help! You wrote "If IC1 in SS1-SS4 is set to switch to the dirt channel"; how can I set it like that? Say concerning a dirty snapshot, I set command type EXT AMP using Instant1 and select "Tip", how does Marshall know in this case that the channel must be changed to dirty (or remain it as dirty if it already is like that)? Till now I have thought that "tip" is always related to channel switch (changes to other channel) and "ring" is related to reverb (that is just a guess). Did you mean I should set IC1 (tip) to all 8 snapshots, no matter are they supposed to be dirty or clean?

I'm thinking to buy Marshall dsl20 cr amp. Let's imagine I have a preset which has 8 snapshots. At top there are dirty sounds (FS2->) and at bottom there are clean snapshots (FS8->). Is it possible to do so that if I use any of dirty snapshots, Helix Floor gives always a "command" to Marshall to use the dirty channel? And, if I use any of clean snapshots, Helix gives a "command" to Marshall to use the clean channel? Just thinking that if this function always switches the amp channel to something else than current, then it is not perhaps what I want (say a case when I have FS2 snapshot on, and I then select FS3 -> would it now switch the Marshall channel to clean channel or not? FS2 and FS3 should both be dirty in my scenario. Should I use TS or TRS cable between Helix and the amp? I don't need FX loop of the amp.
