Building The Board Part 1 - DIY Pedal Looper

Ever since I started playing the electric guitar, I've been a big fan of guitar pedals. My first pedal was the Arion Metal Plus distortion. My setup or rig during my teen years was so simple yet so effective (for me). It was just a fender strat guitar thru the Metal Plus and a solid state amp, fool proof and worry free.

Guitar playing back then was so exciting, productive and lots of fun until I started to adding more pedals into my setup. I played less and less as I spend most of my guitar time chugging a few power chords and tweaking the pedals to my liking. But in reality, all I need is a dirty sound and a clean sound. What frustrates me the most is when I chain the pedals, even with true bypass, I felt (or hear) that the tone of my guitar becomes more washed up with more pedals in the signal path. I think it has to do with the non-soldered contact points with the patch cables and the floor noise generated within the circuit of pedal itself.

The Tone

During the years of playing in a band or even by jamming with friends, the most enjoyable and memorable performance is when I don't have much gear onboard. I remember playing just with my Tele and Peavey Classic 30, cranking the amp up till I get a good loud distorted tone and clean it up with the guitar's volume knob. Talking about minimalist, an electric guitar thru an amp is as pure as you can get. And since then, I've been more of an amp guy rather than the guy with a big pedal board when it comes to tone. Even with the jam groups that I've been into lately, I'd bring my modified JCM900DR and an MXR Zakk Wylde overdrive into the studio and watch the grin on my everyone's face in the room when I start to play some tunes.

The Looper

I have a few 3dpt foot switches laying around from my previous ventures and I've acquired a few more stomps lately. I really want to use/maximize the pedals when I get a chance to join in a band again but I don't like the tone being sucked out by the chain from my guitar. "So, why not get a looper?", I told myself. Ebay had some nice bypass loopers for cheap but it I want something that will fit my needs. I want a looper that has a bypass all switch, that can act as footswitch to my amp (JCM900 or Carvin Legacy) and has an isolated loop for the amp's FX loop.

So the plan, instead of a 8 loop system, I only made 4 with a few additions

A cable would be running from the guitar to the looper and four cables from the amp. The amp would have the cable from the looper, a cable for the footswitch and a pair from the FX loop.

The gut shot

I've learned a trick on how to silence the other pedals when they are being bypassed. It's just not enough to disconnect the input feed from the circuit. Especially with boost, OD and distortion, they will just hum and the active path in the circuit will pick up the noise. To silence them, you have to ground them.

How it Supposed to Work

My pedal board is still in work. I'm still waiting for supplies (cables and connectors) I bought online. But the plan is ...

Guitar ->> TC Tuner ->> Looper - >> Amp >> FX Send ->> EQ Pedal ->> Looper ->> FX Return

Loop 1 - Zakk OD or TS808 Clone
Loop 2 - Wah + Whammy
Loop 3 - DS1 mod
Loop 4 - i dunno, a Phaser or Compressor?
Fx Loop - Chorus + Delay

How it should look like

In the next installment, I'll probably post a video of a working demo and a schematic of the looper so stay tuned.

Crate V33H

Another amp head. I think it's amp head number three for me :D or four?



I've modified this amp to "SLO" mod. Demo.



Features:
- 33 watts
- three (or four) 12ax7 preamp tubes
- four el84 power tubes
- massive OT and PT
- reverb tank

Internals


If you want to to the mod, the schematics is here.

Again, HIGH VOLTAGES INSIDE AND CAN KILL YOU. If you don't know about electronics then do not open your amp. I'm not responsible if you kill yourself.

Bugera 6262

Got this two months ago. It's cheap and sounds good IMO. Here's a demo



Features:
- two channels (clean/crunch and lead)
- seven 12ax7 preamp tubes
- four tube doctor branded 6L6GCs
- massive PT and OT
- 120 watts with 6L6s or 100 watts with el34s



I replaced the stock tubes with JJ EL34s. At one time I had the tubes biased a little too hot, that I almost cooked the amp. Sounds amazing though. For those who want to replace the stock 6L6 power tubes with EL34s, I recommend a bias voltage of 42v.

Love 'em vacuum tubes.


I also made some modifications to this amp to give it a little more punch. By replacing the 1n4007 rectifier diodes with ultra fast uf4007, gives this amp a cleaner sound and a big "thump" in the bass section. I also replaced the cheap MIC filter caps with better ones.

IF YOU KNOW NOTHING ABOUT ELECTRONICS THEN DO NOT OPEN YOUR AMP!!

High voltages inside and can kill you. Seriously.

Chinese Democracy



This album is amazing. Truly a new sound for GNR. Headed by Axl Rose and with the help of Bumblefoot/friends, I really don't miss Slash and the old guys.

For those who keep on whining for Slash and the old guys, please grow up.

where in the heck is my psp?

Updates.

Two months ago I went back home to Manila for a three day vacation.

Then went to London UK for a week of training. It was a blast. Got to see London (and the bridge, LOL), Big Ben, ride the London Eye and Stonehenge. And the icing on the cake, get drunk in a real Irish pub.

Then went back to Sydney.

I Became a dad. Can't wait to go back home next month to Manila. Still waiting for my daughter's passport. Have it stamped so they can move back here with me.
