DIY ebay tube preamp

Watched this video, decided to build a little preamp Currently have an orange or120 baxandall tonestack in there, but with the screw pin headers I can easily swap things out. I wired a A1M potentiometer master volume after the output of the preamp(knob is on the right face of the enclosure) the power jack is on the left face, connected to a jameco 12v ac power adapter. I drilled some holes in the enclosure near the tubes to help with heat dissipation. The input and output jacks are switched from a typical pedal, I originally intended for this to sit on top of my amp. The switching is just a dpdt toggle switch that shorts input to output on one end and sends them through the signal chain on the other.

In terms of issues, I haven’t really been able to push the tubes into proper clipping and they’re definitely low gain, it is originally intended as a hi fi pre so. Yknow what can you expect. Also the AC power leads to lots of noise, even with it switched to bypass, particularly if the treble control is set to max(tbh im not entirely sure why)

Controls

Gain

Treble

Bass

Output volume

Sound Clip(details under cut):

Guitar: Squier contemporary stratocaster HH, bridge humbucker, E standard

Volume max, gain 6, treble 8. Bass 9

ran into amplitube v with the amp bypassed straight into the orange ppc412 cab emulation, mic details were left as default.

Catalinbread Naga Viper (clone)

A nice rangemaster treble booster with a lot more control than usual. The range control is really useful in giving this a good breadth of use, especially when stacking dirt/gain pedals.

My first project, though my first few tries failed so it was not my first finished.

Controls

Boost (level control)

Heat (not sure, probably some sort of pre-boost gain

Range (I believe controls the frequencies getting boosted)

Sound Clip (details under the cut)

Guitar: Squier contemporary stratocaster HH, bridge pickup, E standard

Amp: positive grid spark, RB101(bogner ecstasy emulation) gain 4, bass 2, mids 10, treble 6, master volume 5.

Clips: 

All controls max 

turning range down to 0 and then back up to 5

Turning boost down to 0 and then back up to 5

Heat down to zero then back up to 5

Earthquaker Devices Hoof Clone

Very light big muff style fuzz, I think the added tone control with the shift knob definitely takes away a good bit of the gain, but I love mids so I can’t be mad. 2n1308 transistors replaced with 2n1306

My first build, only real issue is the 2n1306 transistors are really big and tend to either touch the enclosure or fall out of their sockets

Schematic

Controls:

1: Fuzz (self explanatory, gain knob)

2. Volume

3. Tone (low pass-high pass big muff filter)

4. Shift (mid shift control. Clockwise cuts, counterclockwise boosts mids)

Sound Clips(info under the cut):

Guitar: Squier contemporary stratocaster HH, bridge humbucker, E standard

Amp: positive grid spark, RB101(bogner ecstasy emulation) gain 4, bass 2, mids 10, treble 6, master volume 5.

Clips:

fuzz 5, volume 5, tone 5, shift 0

fuzz down to zero then up to 10

shift up to 10 then back to 0

tone down to 0 then up to 10 then back to 5

Bonus Clip:

Getting that heavy big muff sustain by pushing the front end with a treble booster

Guitar: Harley benton MR-Classic, bridge p90, C standard

Amp: positive grid spark, AD clean(orange ad30 i think emulation) gain 10, bass 4, mids 10, treble 6, master volume 5.

Treble booster(naga viper): heat 10, boost 10, range 3

Hoof: fuzz 10, volume 4, tone 5, shift 0

Welcome to the sideblog

loss of knowledge is a top ten things that keep me up at night, so i thought I would document my diy projects, particularly those that i’m finding little to no information o how to do, in the hopes that if someone out there wants to do the same thing, now they have the info! also i have nowhere else to put these things and that’s sad cause i love them

uhhhhhh i’ll figure out organization at some point👍

knob values in posts are from 0-10

Resources and tools I use below the cut

Resources:

Tagboard Effects: Stripboard layouts for guitar pedal circuits (alternative)

Tayda: Great place for all electronic necessities(most common transistors, diodes, and ICs can be found here)

for rarer parts, particularly germanium parts, I'd recommend smallbear and stompbox parts

Guitar amplification and effects: a course by Professor Aaron Lanterman over at Georgia Tech, he's got plenty of great videos to go down the music tech rabbit hole but this course in specific has been very interesting, highly recommend

AMZ fx: a great resource to learn about pedal circuits and how to modify them, would highly recommend their articles on various kinds of clipping/saturation controls

ESP audio pages: a GOLDMINE of information, particularly when it comes to straddling the line between the nerdy electronics theory behind circuits and practical/understandable(relatively) knowledge. everything is explained in enough depth for you to be able to get hands on and know what to tweak and why. they have great articles on circuit sections/theory, and plenty of incredibly useful projects

Tools I use:

Soldering iron: pinecil v2

Solder: rosin-core kester 63/37 .8mm

Wire: small bear tinned solid core stranded
