Peavey MegaBass Club

Just found these scans of an old ad for the trusty MegaBass, so I thought I'd upload them here.

Agreed--$225 is higher than I have seen recently, but worth it if the unit is in good shape. I sold one recently for $150.

I recently grabbed an SWR 2x10 that has a max rating if 200w. (Great deal I could not pass on it). The Mega is the only amp I own that will work with it. Sounds like a million bucks with the mega--my new practice room rig. If I find another one of these it will make a nice vertical 4x10.

I love the flexibility/versatility of the MegaBass!

I'm new here but I'd like a number if you are still giving them out. I bought my MegaBass for $30 on craigs list about 3 months ago. I actually had no intention of buying it and did not know what it was but i figured at that price what did I have to lose. It sounds quite good considering the shape it is in. The EQ is pretty much non functioning. I will be taking it to my amp tech friend to be refurbed. Looking forward to finding out the actual full potential of this thing.

For those guys with service issues, Peavey still repairs the MegaBass heads at the factory. And not surprisingly, they don't charge as much as the local repair guy simply because the replace parts, not repair them for the most part. I have had both my MegaBass heads worked on by the factory for far less than I had paid a local but very good tech who kept having issues repairing them.

Go to Peavey's website and look for tech support contact info. Call them for a fast answer as to where to send it and then they will have you pay with a CC or DC to ship it back. But do keep in mind, any repair on any amp will run you about $200 plus. And if you can find another working MegaBass.......do the math to keep it real.

I know I will not repair mine again. They are great amps they deliver, but there are better sounding amps now that weigh a third the weight. But I'm not saying I would not drop $75-100 on a used one ever!
 
I just bought one of these yesterday afternoon for $200 with a neat little Road Runner gig bag. More than some of you've paid I guess, but I used it last night at a sloppy rock gig into an SWR Henry the 8x8. It's a little well-used looking, but so far seems in order after doing a gig with it last night. The Gain was up halfway and I couldn't believe how loud it was. Jaysis H!! :hiding: I turned it down to around "2" and it was still very present. I was running a 4 ohm cab out of one side...

I'm still figuring out how to run it- gain structure and all. Didn't give myself enough time to get it together, just showed up and hit it!

I'm just making sure everything works right on it over the next couple days- I'm busy as a weasel in a hen house with family and work all around, but I'll get to it! I noticed the sound was quite mids-strong, but maybe that was because I had the "Punch" toggle 'on', maybe it was the Henry, maybe the bass... anyway I'm hopeful this is a winner.

I've got another cab to try it with, and will do the whole A/B thing. I may pass along the SWR SM-400s to my string harp-playing daughter if this is 'all that'- it'd probably be a great head for that purpose, it's so clear and even sounding. Anyway, a photo will come along...
 
Yeah I'm a little ashamed of myself, but it's still, as you say, a bargain really. I just downloaded the manual, and think maybe I should have used the 'High' side for output to speakers in Full-Range mode, but again, I'll be tweaking up this week.

It's heavy compared to what's popular nowadays, but maybe that's transformers? Might be the source of all that apparent power I imagine. Thing's a sledgehammer...
 
I'm pretty sure if you plug into only one of the two channels it automatically bridges and you get 400 watts. Although I think you also have to hit the push button on the front that tells the unit that you are only using one output. Check the owner's manual. Or I will and post.

Nope, they are independent on not bridged in any way. I can see how you might think this, though, as one of those 200w amps is louder than a 500w I have!

P.S. I linked to the manual and a "primer" video I made about this head. While my video isn't the greatest thing in the world, it tells you all you need to know about the thing in a few minutes:

I had a feeling Steve was going to weigh in on this one. I certainly cannot give the full explanation for why and how this works, but in the 'post gain' section of the amp, you engage the small square button so that the amp works 'full range'.

Or better yet, watch Steve's video and/or go over the manual.

This puts it in dual-mono mode with 200W from each output. To utilize the full 400W, you need two 4-ohm cabs.
 
Full range just bypasses the crossover, sending the entire signal to both amps; in bi-amp mode, the unit sends high freq signals to the top amp and low freq signals to the bottom amp. But each amp is 200w always. Again, a very LOUD 200w!
