Hey guys, I've been been using the 1001RB-II for over a year now. Now, I love the tones I'm able to get out of this amp. However, through this site, I've recently discovered the Thunderfunk TFB750 & the sheer versatility this thing seems to have has got my interest peaked. The ability to really dial in tons of different sounds with the semi-parametric EQ section has really got me excited. My questions are.... Are there any huge tonal differences between the GK and the Thunderfunk amps? If so, what? Given the large price differences, what makes the Thunderfunk "better" than the GK (barring the aforementioned EQ versatility)? Thanks.
