Sorry, no pictures nor sound clips – yet – but I wanted to get out a first impressions post on this wonderful amp.
Personally, I’ve never heard or seen a real Dumble Steel String Singer other than Doug Doppler’s video of one of Henry Kaiser’s SSS, so I can’t really make a comparison between Sebago’s amp and the original. But if I were to sum up what I’ve heard from Bill’s newest amp in my short time playing with it, and if you don’t want to read any further, all I can say is that this amp sounds like nothing I’ve ever played before; presenting a complex and rich tonal palette that truly gives it the ability to be used in ANY type of genre. And make no mistake, it doesn’t lean towards a particular camp, as in Fender or Marshall. This amp has a sound all its own, and it has completely blown me away!
I don’t say that lightly, by any means. I’ve tended to be a bit jaded with Dumble-style amps probably due to all the hype that’s associated with them. And though it could be argued that Sebago is doing yet another knock-off of Dumble amps, I believe Bill Dunham’s approach is not to create pure clones, but rather to create great amps that he believes capture the spirit of a Dumble amp; and not be an exact reproduction. At least to me, being a copy-cat is absolutely boring, and Sebago amps are far from boring.
Before I get into discussing the amp further, let me go through its features:
- 100-150 Watts (150 with 6550’s) from 4 power tubes
- Reverb “loop” with send and receive knobs
- Single input with switchable FET circuit
- Gain control
- Three-band EQ
- Bright, Mid, Rock/Jazz mini toggles
- Master control
- Presence control
- Individual High and Low notch filter knobs.
- Power and Standby switches
When Bill first contacted me the other day about the new amp, I asked him if it would have the FET input. He replied no, but when he delivered the amp, he had constructed the FET circuit. I’m glad he did because it tweaks the tone in a very nice way. Unlike an original Dumble, the FET circuit on the Sebago amp is relegated to another input. Bill instead makes it an activated feature via switch (either push-pull or footswitch). According to Bill, the FET provides some extra gain at front-end that produces an asymmetrical clipping that’s not quite distortion though you know something’s happened. To me, it “feels” like a compressor as when it’s switched on, the tone feels much richer and fatter. If I were to own this amp, which I probably will in the future, I’d probably have the FET on all the time.
The distinctive thing about Dumble amps is all the EQ tweaking you can do. The Overdrive Special has the three mini toggles plus the three-band EQ knobs. But the Steel String Singer adds two incredibly useful High and Low notch filter knobs. I believe these two filter knobs are responsible for making the magic of this amp, and these are the knobs that I played with the most, once I set up the EQ. Having the filter knobs really helped me dial in all sorts of tones from spanky, sparkling cleans to big bottom-end crunch – with a Strat, no less! The Low notch acts like a cut, where the High acts like a midrange voicing knob that you find on various amps. The combination of these two allow you to adjust the amp’s basic tone to fit your guitar and cabinet. For instance, I’m playing the amp through my Avatar 2 X 12 with a Celestion Gold and a Jensen Jet Falcon. Even with the Falcon, which has a lot of bottom-end content, the cabinet tends to be bright. But a few clicks of the Low notch filter helped bring out the lows. Just incredible.
As far as the reverb goes, I dig that it’s in a loop, and that you can control how much signal goes into the tank, and control how much gets added back. It allows for really fine control of the reverb, and I spent quite a bit of the time playing with it to see what it could produce. In the end, I set the Send to about 10-11 am, and just twiddled with the Receive to control how much I reverb I wanted to add back into my signal. Very cool.
So how does it sound? With cleans on a Strat, it is other-worldly. There’s so much harmonic content in the signal that depending upon how you set the notch filters and reverb, you can get almost a chorus-like effect which is absolutely dreamy. But you can also get spanky country cleans again, by adjusting the notch filters. Those really give the amp its personality. As far as dirt tones go, as Bill put it, most of the harmonic content is in the preamp section, so you can crank the preamp and keep the master down. Me, I like cranking the power tubes to get them working. But either clean or dirty, there’s a real depth; almost a 3D quality to the tone that’s total ear candy!
With both the Gain and Master cranked, I have to admit that the amp doesn’t sound all that good. The overdrive sound becomes really muddy, and even more so with the reverb on, and no amount of EQ would clean it up. But backing off the Master to about 2:30 to 3pm, gave me a nice, ballsy growl. Can’t wait to try that out with my Les Paul.
Bill did say that at least to him, the amp is a great pedal platform, and that putting a Tube Screamer in front of the amp can get you that SRV tone. Based upon my eval thus far, with the FET and a Tube Screamer, that may just be true. There’s TONS of clean headroom with this amp, so using it with pedals will be ideal.
I found that the sweet spot of the amp is setting it at the edge of breakup with the FET on. In addition to the aforementioned compressor-like quality the FET introduces, the clipping gives the signal a bit of “hair.” I wouldn’t necessarily call it breakup, but you know there’s some distortion. It’s a great tone that I hope to be able to capture once I make some recordings of the amp.
Gawd! I know I’m loving a piece of gear when I write a lot about it. This amp has so much character, and I have yet to really do an exploration of it in both the studio and at a gig, which I will be doing this weekend. I am SO looking forward to playing with it more!
By the way, the name of the amp obviously will not be “Steel String Singer.” Bill has told me what he intends the name to be, but I won’t share it until the product’s actually out the door. It will have a Southwest-flavored name in celebration of that SRV tone. But make no bones about it, this amp can do way more than the blues.
And thank goodness I have my Aracom PRX150-Pro attenuator. I could not do the dirty tests without breaking windows. 🙂

As an active performing musician with 75% of my gigs being solo (I do roughly 200 gigs a year), I’m always looking for ways to expand my musical offerings either by introducing new material, or adding new gear. A few years ago, I started using a looper, and that changed the game for me; allowing me to solo over chord progressions I’d come up with live. But one thing that I missed, especially for certain songs, was percussion. Enter the BeatBuddy.
Got a call over the weekend from Bill Dunham at Sebago Sound who wanted to tell me that he was releasing a Steel String Slinger based upon the topology of a SSS owned by a well-known, grammy-award-winning, blues/pop artist (I know who it is, and based upon the description, you should be able to figure it out).
Though I’m pretty satisfied with my current rig – actually, I’m pretty settled now as far as pedals are concerned – that doesn’t mean that I don’t look to see what’s out there. While surfing this morning before going off to work, I came across the new Voodoo TC line of pedals from Roger Mayer. These pedals feature huge knobs for changing the main pedal parameters, and they’re meant to be changed with your foot!
