I have a Traynor DB800H hybrid bass amp (head) that I bought new earlier this year along with an extra tube (ECC83S installed) and a rack bag. Pictures are attached (bass, cabinets, cables not included).
This is a really pro piece of gear, but much much more than I need. It would really suit a loud rock setting and would make a great backline head in a studio. It's a monster, especially the grindy-distortion.
I am asking $650 (it goes for ~$750 online without the rack bag or extra preamp tube). I might consider interesting trades, maybe an electric bass or an electric upright bass. Maybe some effects pedals or studio equipment - make me an offer.

I have to thin the gear herd a bit and this is just too much amp for my simple needs.
