Thanks, but I've decided I want to add an on/off switch. I have a 3 way toggle laying around that I can use, any ideas on what I could use the third position for? on-off-? I cant use it for a coil tap, I'm pretty sure you need 4 conductor wires, which my humbucker doesn't have.

I need help with some guitar wiring. Can anyone draw up a schematic or explain to me how I would go about wiring a single humbucker directly to an input jack, no switching, no pots.

Thanks

Yeah, the 10k is a resistor, you had already told me and I completely forgot. Alright, thanks alot for the help  :)

<edit>Forgot to ask you this before, but do the pots, input jacks, etc. from smallbear come with the nuts to secure them in place? How are the LEDs secured in place? I'm pretty sure they use some kind of ring. Also, do you have any sound clips of your 5th Gear? Thanks.

Alright, I'm going to buy the parts probably by this week, but I'm a little confused.

- For the 0.047uf caps, which should I buy? Or does it matter? These are all the .047 caps I could find.

- For the pots, does it matter if it's single or double gang? The pots come in 16mm and 24mm. Does it matter which size I get? For the 10k pot, which type should I get? Linear, audio, reverse audio, etc?

- For the 9v battery snap, does it matter if I get #22 or #24 leads?

- What kind of wire should I get?

Sorry for all of the questions, I just want to be sure I'm getting all the right things when I order.

No, I actually plan on using it, so I'll get an enclosure. Two more questions: Does it matter which jack is stereo and which is mono? Also, I don't think your schematic shows the DPDT switch, so how would I go about wiring that?

Alright, thanks a bunch for the help. Any recommendations for where I can buy the parts online?

Ok, so to build your pedal, I think I would need:

- x2 1/4" jacks
- x2 0.047uF capacitor; what voltage?
- x1 22uF capacitor; what voltage?
- x1 1n914 diode
- x1 red LED
- x1 MPSA13 Darlington transistor
- x1 2k linear pot
- x1 10k pot
- x1 100k audio pot
- x1 9v battery connector
- wire
- enclosure
- knobs


Do I got that right, or am I missing something?

Thanks for responding :)

As far as your overdrive schematic, I see the circles on the left and right side are the line in and line out, D2 is a red LED, and I'm assuming the straight lines are wires. Like I said, I really don't know much, but I'm willing to learn.

<edit>After searching Google, I've found out that 1n914 is a small signal fast switching diode, and that MPSA13 is a NPN Darlington transistor. Not that I know what any of this means, but I guess it's progress.

I've been looking into building a guitar amp for the past couple of days because I figured it would be a cost-effective way to get the power I need (I'm going to build an amplifier for live performances, I don't need another practice amp), plus I enjoy DIY projects and I figured it would be fun.

Let me get some things out of the way: I have no experience with electronics, including soldering (I do own a soldering iron, not sure if the quality is good enough to build an amp with though), and I don't know how to read a schematic. I'm an absolute beginner and I know next to nothing. I've already read most of the pinned topics here, but I'm still pretty lost. Any recommended reading for information on schematics, general electronics, soldering, etc. would be appreciated.

The only things I know for sure is that I want something around 100w, +/- 20w would be fine, and I would like two channels, one clean, one for distortion. I was looking at this page: http://www.oliveaudio.com/index.php?page=3, and the second one down can put out 110w with "IRF540N / 9540N". Do you think this amp would be easy enough for a beginner like myself? If not, any recommendations?

Thanks,
Andrew
