Peavey Delta Blues Amps??

Not much difference. I can't recall if they have vibrato channels. Otherwise, the 1x15 is basically a working man's Vibroverb with an added OD channel. The 2x10 is a working man's Vibrolux Reverb with an added OD channel.

I had the former. It suffered from tube rattle, a problem so common that someone I recall actually designed an aftermarket cage to secure the EL84s in the chassis. After I fixed the rattle, no issues.

I regretfully sold mine. I'd probably scope out the 2x10 if I had to replace it, I love 10s in a combo guitar amp. Exhibit A:

I've always liked peavey.

I started out on a Peavey Bandit 65, I got a lot out of that little amp.

May get another one someday

The Super Reverb is the greatest amp of all time. I love 4x10 amps.

The sweetness of 10s in a Fender-style combo and what I anticipate is your price point is exactly why I gave a thumbs up to the 2x10 format Delta Blues.

Most of the clean used 2x10 DBs on Reverb right now are less than 1/5th the street cost of the cheapest price you will pay for an amp like the one pictured above. And that's before you play for the servicing a new-to-you 50-plus year old amp may need. Like a classic car, a vintage amp can be a money pit to get up and running.

The Peavey brings a lot to the table the Super doesn't . The DB more versatile thanks to two very different channels, a helluva lot easier to move around a house or practice room, to haul in a car or up stairs, to retube affordably. And DBs are newer meaning less likely to need servicing, a filter cap job, dry-rotted or played-out speaker replacement, etc.

I have absolutely zero need for another Delta Blues but I will buy the next clean 2x10 that shows up close to me, just to have it.
