I'm looking to make a combo amp using either my Thunderfunk TFB550 or GK 800RB. My criteria is: a: Light (so probably Neo) b: loud c: wonderful tone (deep, ballsy, punchy) d: quality construction of course I own both of these rackmount heads and plenty of speakers for the larger venues but need something for the smaller club gigs. Leaning toward a 1x15, 2x12 or even 1x12 if it's strong enough. I play with two bands, one has two horns with a four piece rhythm section, the other is a classic rock and soul unit with two loud guitars, so I need something that won't wimp out! Any ideas and comments will be greatly appreciated.
