TREBLE BOOSTERS

A cool feature in the Kalamazoo overdrive is that it incorporates both a treble booster and a conventional tone control on separate knobs. This tone knob is not for adding bass back in like the ones shown in Pete's demo. Both knobs work in the treble but one is pre-drive, the other is post. So you can tailor both breakup character and overall brightness. Not intended as an always-on unit like the Rangemaster, though I suppose it could be used as a foundation drive.

I've got two variants of the Kalamazoo: a single (the Black Magic version) and another in the Box Of Awesome dual pedal.
Excellent lead drives that have the treble boost circuit to thank for their somewhat unusual personality.

Big fan of Lovepedals; I have quite a few and there isn't a dud in the bunch. The Kalamazoo is one of my favorites.

My only standalone treble booster is The Creamer, a handwired clone from Devices Of Rawk in Greece.
It does what it's supposed to, and does it well. But for the most part I don't need it.
 
Ordered a 65 Amps Colour Boost germanium treble booster from Sweetwater today. They had 'em marked down already, and I got word that they were accepting lowball offers on eBay. $80 for a pedal that lists for $225 and normally sells for around $150. Free shipping too. Couldn't resist.

I wanted a Colour Face (germanium fuzzface) too, but Sweetwater had sold out. Those go for big bucks used, and $80 would've been an absolutely screaming deal for one.
 
Been using the Tony Iommi Laney TI-Boost #31 first batch

Finally got around to watching Pete Thorn's excellent Treble Booster video. PT certainly nailed Brian May's, Iommi's, and early Judas Priest tones. I was waiting for a Rory Gallagher example, but to no avail... :(. Love, love, love, treble boosters!!!!

My Catalinbread Naga Viper and Rangemaster (by Don Butler):

AFAIK, the Naga Viper is definitely a Howard Gee designed treble booster based on the original Dallas Rangemaster with added tone and boost control that work very well. Plus, Catilinbread is known for stuff like this Black Sabbath quote on the back of the circuit board:

I got my Don Butler-built Rangemaster in '06. The following year, he stopped making them because he said that sourcing NOS Mullard OC44s was too problematic. So, I'm assuming that's the real deal hiding inside the pinkish heatshrink tubing:

I agree with you about nailing it! :dood:

I like the fact Pete puts the Treble Booster in Rock context, with when, why and who used it, with what gear and all with stellar examples.
Need more informational videos like this from the correct period in which gear was used.

Better understanding leads to Greater Tone! :dood:

Ivan your clones look real or original

I go for NPN transistors like the Mullard OC140

Thanks Mr Plexi.
It appears that you got those from the same place I got them. I like that he supplies the resistance values for proper bias.
The power units under my board have a couple of switchable polarity (& variable voltage) supplies so using PNP's & positive ground effects isn't a problem.
I do have a Mullard black glass CV7003 (military spec OC44), 96 hfe & very low leakage current in my parts stash that I haven't yet put to use. This thread might be the inspiration I need.
