The return of Sunn amps?

Well, I was curious, so I bought one of the footswitch and cable bundles and got to run it through the paces last week.

Bottom line is that it wasn't right for the application I was hoping for. That said, the amp, footswitch, and cable are all made in the USA, and the build quality is impeccable. I really wanted it to work out and the tones are incredible. I never owned one of the originals, but Sunn customer service said that the footswitch and cable work for the vintage amps as well as these new reissues.

The distortion / fuzz /overdriven tones are very unique and crushing. Both channels run together is an incredible sound and can create that two amps running in parallel sound that I prefer to a clean blended pedal etc. Depending on how you set A and B in relation to each other, it sounds like a pair of amps run clean and dirty, or it gets into sludgy mayhem if you overdrive both channels.

So why return it? I was hoping I could set one channel clean, one dirty, and then blend the two for three distinct tones. With my gear and my intended application (READ: really loud drummer), the channels run independently were not loud enough on their own. Or at least I couldn't get the clean clean enough for the three distinct gain stages I was going for, and of course, YMMV. I tried it at home with a passive p-bass, and at a rehearsal with a Ric 4004 Laredo, for reference.

The summed channels were HELLA loud, and if I was only going for one tone, that would be a killer tone to go for. The effects loops (one on each channel, plus a master) were a cool option, and had each channel had enough juice, I may have been able to play without a pedalboard, but it wasn't meant to be for me. If I was playing in the right kind of band, this would be a killer rig, and again, I can't speak highly enough about the build quality. I have paid $1k and gotten a lot LESS amp in the past…and that was with something made overseas.
 
Sometimes you have to make your own return!

Here's my 1969 Sunn 200S:

I decided I wanted a small project and picked this amp up a few weeks ago. After some initial testing, I recapped the bias circuit and the first stage of the power supply. Replaced a few dropping resistors to keep the voltage on spec. Installed a three-prong grounded plug. Biased it into a reasonable zone. Pulled the original Mullard KT88s (one was red plating) for a pair of USA GE6550s.

She's a keeper. :)
 
I think I need to amend my previous "review" as I had a studio session where I ended up bringing the new SUNN BETA BASS and gave it another try. I maxed the gain on the Sunn and made it my always dirty amp, and then had a second amp set clean. It performed wonderfully and the distorted tones made my usual dirt pedals superfluous.

Before the session I was playing around with the head in a live setting and think I found a way to balance the two channels. Unlike my unsuccessful prior attempt, this time I was able to better balance the two channels for one clean and the other dirty. Then I used the master volume to match the band's live level and I was happy switching back and forth between clean and dirty. When the two channels are bridged there is still a big jump in gain, but I used that as a boost. This is a power trio, so I often use a boost pedal when the guitarist goes to single notes to fatten things up. I used the bridge in lieu of the boost and I think it made this amp a keeper for me. Moreover, I think I may try and utilize the three independent effects loops as I am loving the breakup from the amp and may rethink my pedal situation.

[This invalid link has been removed] has a decent pre-order price right now. They are scheduled to ship 3/1

I have a recent reissue big boi and just jumped on the preorder.

I'm interested! The channel blending and switching could be very practical for my semi-Ric-O-Sound playing. I wish it could have a bit more power, though: 200 W is more than enough for doom guitar, but a bit more wouldn't hurt for bass especially since Class D power isn't exactly heavy.

this will tell you how old i am, i bought a sunn 2000s head for 125 dollars at musician's bargain basement in kenmore, OH, because I couldn't afford any ampeg

my friend sold his sunn beta head for 175 dollars, because he could afford an ampeg svt

i don't want to hurt anybody's feelings, but considering the price, i'd just slap a sunn sticker on a tc electonics head and call it a day ;)

Playing these heads tho... I'm not wishing it had any more power. :laugh:
