Ones I regret now selling: Hilgen Basso Grande - my first amp - used it as a bass amp and it would be great to have for guitar again. Rare and hard to find. Music Man 65 410 - My guitar amp for high school and college - great cleans and a half power switch. Sold it when I moved to Hoboken to a 5th floor walkup and moved to rack for a while... Regret it being stolen from me: 65 Bandmaster - rebuilt, put into a Newell 2x12 cab with Warehouse G12C/S speakers. No regrets: 65 Showman - great amp, but way too loud for my needs and had bought it when I thought I needed to have all the '65 Fender amps '59 Bogen Challenger - great raw PA head converted into an amp, but I never played it. Sold it for the same amount I bought it for. Fender Bronco tweed - good practice amp, but when I got back into amps vs. rack I then went back to older Fenders. Dr. Z Mini - great amp, but replaced it with a MAZ 18. ADA MP1 - my guitar sound for 92-'09; have it pretty much in my Avid Eleven Rack.
