Thank you, it's all been recently acquired and so much fun to play with. I've been waiting a long time to pull the trigger on better gear than I have ever had. I ran a peavey 115 combo for a while then a TC Bg250. Then that acoustic held it down for a bit. I have wanted a good amp for a long time and I said screw it and jumped on a markbass. This is actually the second I had the 102p but it has a speaker wire issue. When I took it in this 103p was on sale for less than i paid for the 102p so I traded it in and got WAY more for a few hundred less. The boss GT1B was my first pedal and I LOVE IT. If you run it through your computer and actually use the program to adjust your settings and pedals it's amazing. A lot of guys in the owners thread have ditched their pedal boards for it and gig/record. It takes patience but it's worth it. And for 200 bucks 100ish used you'll get more than your monies worth. I'm using the Para EQ and a preamp sim for my clean tone with delay, reverb, flanger and phaser just a stomp away.
I have another patch set up for hip hop or techno or lofi stuff with octaver, synth, and a boost assigned to the stomps. The effects are modeled after not only boss pedals but there are sans amp, big muff, MXR, markbass etc. give it a shot you'll enjoy it.
I don't have any experience with the ZOOM i am aware of it and it seems 50/50 on preference between the two options from those who have used both, neither being bad at all. GT1B has some extra features that the zoom doesn't but some prefer some of the sounds on the zoom and the operation better. I dunno, I spent hours and hours adjusting each effect to where I want it with the goal of not having to tweak anything once I've stomped on a button. Now i have 6 stomps each on two custom patches so 12 "pedals" for 200 bucks plus another 50 for the foot switch. Vs the cost of buying one of each pedal?
