I am currently running an Ampeg B5R all by itself and, IMHO, it leaves a bit to be desired in the tone department. Now, I'm considering buying a new SVP-PRO to try and warm up the tone (via five 12AX7s) and provide for more flexible tone control (via 9 band EQ). To sum up, I want the resulting combination to provide SVT 3 tone control with B5R power. Should I do it? Will it work? Anyone who's had experience with the preamp (especially in the context that I plan to use it), let me know what you thought! Any and all feedback will be appreciated!
