Bass Boost Pre-amp/overdrive pedal build - basically a tubescreamer circuit with 2nd op-amp chip driving an active treble and bass controls. Input cap modded to select normal or phat mode for fuller bass drive, via mini toggle switch. Switch is connected to bi-colour indicator LED to show mode selected. 1. PCB populated and all wiring attached.  2. Enclosure sanded back, cleaned up and drilled via template holes printed off from computer.  3. Artwork attached - inkjet-printed clear adhesive film, fixed with a few spray coats of clear acrylic lacquer  4. Circuit connected to jackplugs and battery to test all is working ok  5. Starting to fill the enclosure, pots first.  6. Everything in place and soldered up, quick test before fitting the perspex glow-plate  7. Finished pedal  |

Dang, Eric, you're getting pretty good at cranking these things out. Seems like a new pedal every week!  The glow plate thing is a neat effect, as I think I said on your last one, don't be surprised if Boss is making them like that soon . . . |

Wow!
Do you do the artwork yourself?
Are these kit pedals?

Yeah. I need to get around to building again. They'll never look as nice as yours, but I'm not really worried about that. It's just that you make me feel like a lazy bastard!
Not to take anything away here, but the glowplate thing is a fairly popular sub-cult in the DIY community. Al won't have a claim if Boss or somebody picks up on it. It'll be more like picking up late on a trend, which is kind of par for the course.

This is a quick demo of the Bassboost pedal using my Fender Jazz thru my little Peavel practice amp. Sound is a bit restricted as its recorded on a mini compact camera, but hopefully it will give you a flavour.
The pedal on zero gain acts as a clean boost, with active bass and treble controls.
The Phat switch adds in a little extra warmth to the bass tone, its subtle but more pronouced at volume through a proper bass cab.
Add in just a touch of gain and you get a nice gritty rock drive. Crank it up for stacks of saturated distortion.
With the gain up, the bass and treble controls add further saturation to the tone; bring them back down to just on and you get a looser harder edge to the distortion.
The pedal sounds great with lead guitar too, with phat switch on it gives a big warm fat overdrive and a bit of mid boost.
Runs off 9V battery or standard centre-negative 9V DC stompbox adaptor.

Very nice little bass booster. I like the phat switch.
You looking for a North American distributor yet?
Gotta +1 you here, just because it's a bass pedal...

thanks guys, if I had IP on the circuit I'd be very tempted to set up a little retail biz in these, they are really great overdrive units. Sadly I am only copying another companys ciurcuit but adding a couple of my own small mods. If anyone is ionterested in putting together one of these I will gladly point them in the right direction  |
