DSM & Humboldt's Simplifer X Zero Watt Reverb Stereo / Dual Amplifier is a magnificent marvel of analog audio engineering

I’m totally in awe of the technical prowess presented on this killer dual analog amps in a pedal format.

 

It’s actually a very compact device at just 125 x 105 x 65 mms, and carries so many advanced functions here almost entirely in the analog domain. There’s not a single sub-menu here - this is surely WYSIWYG perfection - while it does use every available surface to cram in all the technology that is needed to support all those features.

 

At first encounter this all seem wholly intuitive...

2024-GPX-Krozz-Devices-Airborn-Flanger-700.jpg

As well documented on this site - I’m a huge fan of the Flanger modulation category - and the Airborn is my own 19th pedal of that genre - where I already own a number of superb High Fidelity Specimens - many with incredibly rare BBD chips onboard.

 

This Airborn itself also has a pretty rare NOS Matsushita MN3207 BBD Chip onboard - which is quite evident from its output on first encounter. Flangers are typically fairly variably musical - while this one is a particularly great example of a ...

2024-GPX-Bleak-District-Miraj-700.jpg

This V2 Edition moves on significantly from the previous V1 - going from 7 to 10 Controls - and introducing a whole load of more colour into the proceedings - both figuratively and literally.

 

The V1 Controls consisted of - Regen, Rate, Volume, Depth, Univibe / Phase 90 Switch, Phaser / Vibrato Switch, Waveshape : Ramp Up / Ramp Down / Square / Triangle / Sine / Lumps / Random / Stepped, On/Off Footswitch, Tap Tempo Footswitch.

 

While the V2 Controls are - Envelope, Rate, EXP Switch : ...

2024-GPX-WEC-Homework-Series-Fuzz-700.jpg

This is one of the very best 2-Transistor Fuzzes I’ve experienced - it pays to check the instructions on this one though - as the Tone and Body controls are both inverted - going from Maximum to Minimum values! That sort of thing can at times catch me out a little!

 

So in one respect this is a Classic Fuzz Face, while in another it’s really a Fuzz Factory 7 style Fuzz Face - with very similar controls to that more evolved circuit.

 

It is therefore essentially my 5th Fuzz Factory proper - ...

2024-GPX-Origin-Effects-Cali76-FET-and-Bass-700.jpg

It seems like the world-beating Cali76 Compact Deluxe FET Compressor is finally about to be knocked off its commanding perch - by an even better engineered and finessed replacement, which now includes a 10-LED Bar Graph Gain Reduction Meter for the first time so you can properly witness this Compressor’s superb agility and speed!

 

Everything you loved about the Cali76 is very much intact on this new model, but with an increased 24V Higher Headroom, further optimised all-analogue signal path,...

An interesting fact is that this collaboration almost happened several years ago, but evidently the timing wasn’t right then for various reasons. This time around though there was an added ingredient in the mix - ’Yours Truly!’ - and I was somewhat instrumental in bringing the two sides together and finally making this happen!

 

It’s great news for us Brits - as these Lastgasp Art Laboratories Pedals have always been somewhat beyond our reach until now.

 

I obviously recently covered my 9 ...

This is truly quite a feat of engineering, and it’s all so beautifully executed too. That said Boss’s Katana : Go had a useful tiny screen, and Bluetooth connectivity to its app - which this devices could really have benefitted from. I’ve long grown tired of having to USB-cable-connect my pedals to a laptop app for updates - it should all really just be bluetooth to an iOS or Android mobile phone app by now.

 

In any case, the operation of this device could not be easier - you first of course...

2024-GPX-TWA-Triskelion-3.0-V2-700.jpg

So back in and around 1975 there was a large aluminium box with red and black graphics made by Systech, and which had an open 9V battery bay built right into the front facia. It had just 3 controls - Bandwidth, Center Frequency, and Gain - which were instrumental in delivering the classic Frank Zappa sound of that era! The Gain knob sweep was fairly expansive, but not too heavy on the breakup until later along the taper - rather an amplitude control for most of the sweep - although it did climb...

I’ve been on something of a Tremolo kick this year - I decided that said capsule collection was a little slim in comparison to my other modulation categories - so I determined that I would focus on Tremolo for 2024.

 

The Drunk Beaver Chernivtsi Trembita Optical Tremolo kick-started this year’s journey, and I already have the Lastgasp Flikrrr and Tru-Fi Ultra Tremolo inbound - which will take that capsule to 15.

 

I had further identified around 8 or 10 targets for the reference collection ...
