I've decided I want to upgrade my rig, so I'm looking for a head that plays nicely with pedals and has a clear, defined sound. So far I've thought of these options: 1) Kustom DE300 (289€. 2) Used Peavey Max 450 (not the current Tour 450) (230€. 3) Preamp based on a Sunn Model T (240€. I would use my current head as a power amp with this one. It would be the most expensive option, since I wouldn't be able to sell my amp (I can get about 150€ for it).
