Treble booster question

[Kipper4]

A buddy has asked if i can build hima treble booster to compliment his Vox AC30 and american telecaster combination.
He already has a distortion on his Boss ME50 and is looking for another lower gain  flavour of distortion so i suggested a treble booster.
I'm thinking Fryer treble booster deluxe with germanium tranny.
But i'm canvasing for opinions on what you would reccomend for this combo and criteria.
I'd appreciate your input
thanks
Rich

The fryer treble booster uses a silicon transistor, so you're unlikely to be able to drop a germanium transistor in there.

I'd suggest you either go for a silicon fryer or a germanium rangemaster, depending on whether you're going for a Brian May or Rory Gallagher vibe.

With a tele you've already got a bunch of treble, so probably worth building a booster with a cap blend mod to move between treble boost and flat boost.

If you want to go germanium, the Red Rooster springs to mind:

I like the Omega from runoffgroove.com. Pretty versatile treble booster, IMO.  Fits nicely onto a tiny piece of Vero and into a 1590A:

Mark i made the Omega as a trial and its very noisy. it has a sort of electrical hum too it it gets worse as i turn up the boost.
I did the layout as per the ROG page except i integrated the pots on the perfboard..
Did you do the perf layout too?

[Kipper4]

I'm not sure i know what i'm on about but it kinda feels like a noisy cap. Does that make sense? Is it possible?

[Digital Larry]

What's the pedal powered by?
Does it hum when nothing's plugged into it?
Does the selection of pickup, or the knob position of volume/tone controls, or the position of the guitar make any difference to the hum?
How exactly did you wire the input and output jacks?  I notice that some diagrams (in general) omit the ground lead to the output, which is OK if you are using metal non insulated jacks and a metal enclosure and tighten everything really well.

Hmmm...  mine was gorgeous and crystal clear.  Did my own Vero layout:

I've got a bit of vero left i'll try it again later thanks Mark

[Kipper4]

built it on vero as per (exception rev pol diode added)
Same thing with the 9v power supply its just too noisy to make use of it but with a battery its excellant.
Its unboxed as yet.
I dont normally get this kind of thing any ideas why i am this time?

[smallbearelec]

with the 9v power supply its just too noisy to make use of it but with a battery its excellant.

What kind of "9v power supply" are you using? An unmodified wall wart could easily be causing this.

[Kipper4]

wall wart but its normally very quite with most of the pedals i make. infact i prefer it over some of the others usually.
this is really annoying.

I was gonna start another thread but I figured this one is as good as any.  I'm looking for a treble boost for my bass.  Basically I want a smooth-ish overdrive for higher frequencies only.  I have a bass booster already and I'm looking to blend the two.  I have an aversion to using any designs that are dependent on components with bad part tolerances so I prefer Si NPN's over JFETs and Ge trannies.

Any recommendations?

I should say that JFETs are tolerable if they get the best sound but Ge's scare the crap out of me.

[davent]

I've found adding a series 100r resistor to the power supply input followed by a 100uf cap to ground has quieted simple builds that were perfectly quiet on battery but annoyingly noisy with a power supply.

My Omega's totally fine too.

Thanks for the tip Dave. I'll make a note for future referance.

Bill theres always the Brian May Treble booster that is silicone based. I've made it a couple of times but with BC109s.
Ive ordered some BC182s now to try it as per the online schemos (Paul in the lab style)

Talk to Smallbear and get one of their Rangemaster transistors (Japanese knock off instead of NOS can is fine, I've used both) and build the stock Rangemaster EXCEPT...

Switch the input cap between .05 and .1 (or .005 and .01 can't remember without notes in front of me).

Push that thing to the edge into a Vox amp and they break up ever so beautifully and subtly.

Mind you its a pos ground circuit which can be off-putting.

[smallbearelec]

Make yourself a little box (can be plastic) that contains a large-ish filter cap, a three-terminal regulator and a small output cap. Wall warts really do need the extra filtering.

[mistahead]

There used to be a simple filter vero floating around, I have it on another PC and cannot for the life of me remember who's it was (I thought Adriano's but I can't see it on a quick skim through his gallery).

Protection diode, filter caps, low parts and very effective for cheap wall-wart issues with gain pedals... Who can find it?

Game on.

Type "treble boost" into the search.  There are a number of TB threads here.
