HELLO EVERYBODY FROM ITALY !!!!!! A question: I use rack system from many years, I like it sooo much , but would like to eliminate Marshall JMP1 for a MESA QUAD PREAMP. Can someone tell me something about this beautiful (2 rack units????) black beast???? How many sounds can I obtain in real time for a live session for example??? (switching through cleans, crunch, rhythm and lead??).Is it possible to obtain some nice lead tone à la Petrucci (Dream Theater????) Does the TRIAXIS work much better????? Thank you in advance to all of you !!!!
