July 2011 Pedal Gallery

My neighbour told me that I've been neglecting the blog of late, so I've just taken a few happy snaps of the pedals that I keep under my desk. This is most of my current working collection. I've built loads more than I have here at the moment and have discovered Circuit Snippets to be a great collection of unusual circuits for processing audio. Whoever the guy is behind it, must be some kind of genius!

Not much has been going on, trying to get motivated to finish my pickup ring templates, and in turn finish modding my Les Paul.

Home made fuzz pedal - A blend of a failed Ampeg scrambler followed by two cascading Germanium Transistor boosters.

Fuzz face clone - Easy face with tone control - Substituted Soviet era transistors for recommended.

Psychtar - From circuit snippets.

DOD stereo chorus - With vibrato mod (my design).

Bronx Cheer - Another pedal from Circuit Snippets

Ibanez  DE7 - Cheap good sounding delay.

Zoom H4n - Not a pedal, but has loads of FX. Good as a Rocktron substitute.

Danelectro Cool Cat Chorus - 18v model. Yard sale bargain.

MXR Blue Box - Two octaves down with lots of fuzz - Great square wave tones.

Fuzz Face Clone - Another fuzz face clone - Soviet GT404 Germanium Transistors. Volume control only.

Belcat Tremolo - Nice cheap variable wave shape tremolo.

Boss SD-1 - Modded clipping stage - Can't remember which mod...

Digitech Bad Monkey - One has been modded to let more bass through - Can't remember the cap value, probably .1uf

Sovtek Big Muff Pie - Indie rock staple. Fuzz Fuzz Fuzz. Works best with low output pickups.

Sovtek Small Stone Phaser - Nice sounding phaser, but has a tendency to generate nasty clipping on the front end if modded to compensate for the volume drop.

Fulltone DejaVibe - Nice Univibe clone. A bit expensive, but worth checking out.

Jim Dunlop Octavio - Fuzz Octave - Unpredictable insane fuzz. Very pronounced octave effect. Sounds different on every guitar.
Legacy OC-100 - Boss OC-2 clone - Might be cheap, but it tracks as well as any pedal. Works great with my stereo flying v!

2009 - Fulltone Mini Deja Vibe2

For years I wanted a univibe clone. Always baulked at the expense.
All of the clones cost a heck of a lot. There are a lot of clones too, so which one to pick?
Obviously I eventually settled on the Fulltone, but it was an almost agonising decision.

The MDV2 costs RRP $565 or there about the last time I looked.
No way was I going to pay that much for what is essentially a glorified phaser.
So I started looking further afield...

USA prices were much more reasonable, and our two currencies were nearly at a ratio of 1:1.
I'd sold a bunch of lesser pedals and had a few $ sitting in my paypal account waiting to be put to use.
There was a shop in Melbourne that had one in stock, but when I went to try it out the sales guy told me it'd been moved to another store on the outskirts of the metropolitan area and wasn't coming back for at least a month. Since my effort to try one out in person was thwarted, the only thing to be done was hit the internet.

Not a heck of a lot of information was available on this unit. Not many demos either.
So it was a bit of a leap of faith when I decided to buy online. It was a little over half the Aussie RRP including postage.

So I bought it and then had to wait....
It seemed to take ages to get here, but in reality only took a week.
The unit is fairly large, with considerable weight.
Nice and creamy coloured and the PCB is compact and nicely laid out.
It's been modified from the original to allow a higher and brighter output if one chooses.

When I finally had the opportunity to play it, I had mixed feelings.
The wobble and whoosh was nice, but on my DI rig and Epiphone amps it seemed to drop a lot of bottom end off when engaged. The MDV2 does the lopsided swooshy throb thing very well. Vibrato mode sounded quite subtle but more of just an add on option rather than a useful effect. I liked it, but wasn't really all that impressed. So for most of the time I've had the pedal, it has remained in a drawer and potentially facing the auction block. Also the phase on the lowest speed almost sounded as if the effect was off.

That was until yesterday....

Yesterday I dusted it off and plugged it into the Delta Blues, oh boy what a difference!
I swear there's something about that amp that maxes everything sound good. I'm not saying magical or mojo, but something fundamental on the electrical level. The difference I suspect is the input impedance.
On a stock Epiphone Valve Jr, the input impedance is about 100k and on the Delta Blues spec states 470k.
The end result is the Delta Blues has a greater frequency range on input and your guitar and effects can drive the valve stage a little harder (The Valve Jr is easily modified to rectify this).

The effect that this had on the univibe clone was an overall improvement in sound quality. The bass cut I'd experienced before has gone away. The phasing at low speed is much more pronounced and the pitch wobble in the vibrato mode is now clearly audible. In fact on both settings, the depth control doesn't need to be on maximum. The effects come through nice and clear, great on clean and distorted alike!


In all, I'm glad I didn't part with the MDV2. It's definitely a keeper.
