Hello Effects Fans!

My goodness – September is slipping away!  What happened to July and August?!?  Soon the boys of summer will be gone and it will be time to wake up Billie Joe. 

I’ve unplugged my iron and am headed off to my island retreat.  This is planned to be a lengthy time away in order to better align my schedule here and there.  While I’m away, I’m still available to configure orders to be built upon my return.  No deposits will be necessary until just before I return and start building again.  We’ll figure out all the details and hold your place in the queue until then.  Of course, non-build items, such as the popular 3U Pedal Rack, can still be ordered and shipped while I’m away.  They are available directly from us and we have a few listed at Reverb.com – just search for “Gerlt”.

We introduced several great new modules this summer.  Several more are also completed.  I just need to get them up on the website and announce them.  You’ll see them as I complete those webpages.  Some additional modules are also in the design and prototype stages.  Some of these are effects I’ve put off for a while because they require unusual or specialty parts.  It’ll take a while for me to sort those out, evaluate new types of parts, design boards for them, select vendors, etc, but they are progressing nicely.

I am also developing a plan to reorganize some of the information at the website.  Some of it would benefit from better organization and presentation, untangling some topics that are mixed together, and generally streamlining it a bit.  I’ll see if I can make some progress on that between Mai Tais, but we need to be realistic here…

That’s it for now.  To get your custom rack setup configured, priced, and queued, just drop me an email at our Support email address.  While the array of options and choices may seem intimidating, it’s actually not difficult to get through.  The modules sound great without any extra options or configs at all, and most of the best options are easy to understand. 

All the best,

Hello, Effects Fans!

Time for a twofer!  Today we announce two new configurations of our Pi module, the P1 Pi and the Corn Pi. 

The P1 Pi compares to the Pete Cornish P-1 Fuzz.  This circuit is a version of the Big Muff Pi circuit, with Pete Cornish's tweaks and his famous input buffering.  You'll know it is in the Big Muff family from its Volume, Tone, and Sustain controls, along with the type of fuzz it produces.  The P-1 was the pedal version of a custom Ram's Head Big Muff that Mr Cornish built for David Gilmour back in the mid 70's.  Back then it was called the Custom Fuzz or Cornish Fuzz, and it was one of the earlier Big Muff Pi derivatives of its time.  It was built into Gilmour's custom pedal board for the Animals tour. There are no clean sounds to be found here, even if you roll back your guitar volume.  It's a fuzz pedal, for goodness sake!  There's loads of Volume and with the Sustain up you'll have as much feedback as you can manage.  The Tone goes from blanket-over-the-amp wooly to bright enough to cut through your band mix.  Maybe a touch more mids and a hair less bass than the usual Ram's Head versions you might find.  The string and note clarity are better than some Big Muff variants.  Sustain forever, if you can keep it under control and you know what to do with that feedback!

The Corn Pi compares to the Pete Cornish P-2 Fuzz, another Big Muff Pi derivative designed for David Gilmour.  It was originally known as the Precision Fuzz and was used when Gilmour toured in '88.  It was also picked out as a favorite by Lou Reed around that same time.  Instead of the normal mids scoop sound, the P-2 has a flatter midrange response, which is a very popular mod for Big Muff derivatives to help them cut through a full band mix.  While Gilmour tone aficionados know that Gilmour's fuzz tone has evolved over time, the P-1 and P-2 are more similar than different, setting aside the flatter mids response of the P-2.  In addition to more mids, the P-2 may have a bit more bass available, but with an overall brighter tone.

As with the originals, our P1 Pi and Corn Pi modules are similar, yet different in the ways mentioned above.  Of the two, the Corn Pi seems to always be fuzzier.  The Sustain control does adjust the gain/fuzz, but an equally noticeable side effect is a change in the Tone.  The Sustain and Tone controls will probably need to be adjusted together.  Outside the context of chasing Gilmour tones, we prefer the P1 by a slight edge for general Big Muff style fuzz tones.  That is mostly because the Sustain behaves more like other Big Muff Sustain controls and is less interactive with the overall Tone setting.  Gilmour has used both versions of the circuit, so you can't go too far wrong either way!
