I have a garnet 2 channel tube amp with no distortion.I bought a mt2 metal zone which is great for metal but i want a classic rock sound also.I want a tube sound and thought about selling the mt2 and getting the vox cooltron bulldog distortion which covers both metal/rock sounds.or would a ds1 or os2 do the job?i also have an sd1 super overdrive.any input greatly appreciated.
