Okay so here's what's up. I have a GK2001 which is pretty cool but i've been playing with the MarkBass TA501 for a little while at my job and I must say... it's seducing me So I'm going to bring in my rig next time i have off from class&work. Do a little comparison with my cab and GK2001 with the TA501. I also need the winning amp to be super clean. The Markbass seems to be making a much better clean tone than my GK. I like the GK but i must say that it can get a little dry. The TA501 has some nice usable features. Does anyone use a Rickenbacker and TA501 and want to give me some previews? And what about effects with the markbass? Since it's super clean, i imagine the effects will sound intense. I also need a rack tuner. Just a simple one so i was thinking the DTR1000 by Korg. Objections? Also will be upgrading to a monster power center. And I might sell the Aphex 204 unless it goes well with the TA501. Any other rack gear i must have?
