Sometimes lots of mandatory overtime has it's advantages. Had a hole burning in my pocket and a need for some effects, so here I am today. Haven't broken it out at home with my own amp yet, but I gave the Boss GT-1 a fair shake today at my local music store before purchasing... Plugged into a Marshall Origin 20 head and a 2x12 Marshall cab. First impressions are pretty darn nice. With the output set to "Stack" and the preamp set to "MS 1959 I + II," it sounded *just* like I had cranked the Origin and let her rip. Setting up a "natural clean" preamp with some Univibe and Tera Echo and using the expression pedal gave me some immensely satisfying ambient swell sounds, with very little "dialing in" necessary. My understanding is that the GT-1 has the same DSP as the GT100 and is also extremely similar to what the Katana uses. I have high hopes for this unit when I really get to plugging it into the Marshall DSL. I'm hoping it will be a really solid, compact solution at church when I want to DI or use very little floor space, or in the effects loop when I want to use my footswitch, OCD, and Crybaby wah. I fully plan to complete my pedalboard with a two-button boss footswitch and another OD (thinking about an EHX crayon to shape my tone a little more before it hits the OCD). Anyway, more thoughts to come later!
