BLUEPRINT

ANALOG-VOICED DELAY

This pedal is discontinued, but it available until November 29 as part of our Klein Bottle launch.

The BLUEPRINT is an analog-voiced delay pedal, perfect for warm, ambient delays that don't muddy up your tone. The BLUEPRINT delay uses a unique EQ method that blends a dark and bright delay, yielding a warm tone without sacrificing clarity. An internal trimpot allows you to adjust the blend to brighten or darken the tone to your taste. Get up to 580ms of delay time, plus modulation for adding slight detuning, warbled chaos, or even pseudo-chorus sounds.

FEATURES & CONSTRUCTION

TrueSoft  Bypass

Low Noise Op Amp

Extended Headroom

DualMode Switching

We combine durable true bypass relay switching with an effect-side FET switch for pure and smooth switching.

A modern, high-speed op amp was chosen for its low-noise and high-fidelity properties.

A simple voltage inverter circuit was used to effectively turn 9V into 18V. More voltage means more headroom & bigger tone.

DualMode Switching can convert the footswitch into momentary operation.

To use, wait 5 seconds, then press the sequence tap+tap+hold until LED flashes.

USA Made PCBs

Our circuit boards are made in the USA by Advanced Circuits (large PCB runs) or OSH Park (small PCB runs).

Analog Dry Path

100% analog circuitry was employed in the dry signal path. Your tone is preserved, with zero digital harshness.

HOW THE BLUEPRINT CAME TO BE

THE STORY

The earliest design can be found in a small batch of dual-pedals I made in 2009 called the "Echo Ohce". The Echo Ohce is the pedal that first put my work on the radar of the boutique industry, and is still requested to this day. The delay in the pedal was paired with a circuit that would eventually become the Bumblebee. Together, these two circuits could create very unique effects, from synth pads, reverse delays, and more.

 

The design goal of the Blueprint was to create ambient delay sounds that give a spacious landscape without getting in the way of what you are playing. The biggest challenge was finding an EQ that produced these tones without going too dark and losing all definition.

-- Peter Rutter, founder of VFE Pedals --

Here is the list of versions of the Blueprint circuit:

 

#1 - When the current control layout was first created, the jacks wouldn't fit into the thinner enclosures we use now. So I combined two effects into one box. One of these pedals was called the Echo Ohce, which combined the effects that became the Bumblebee and Blueprint. The original Echo Ohce a flashing LED that pulsed in time with the LFO circuit.

 

#2 - The second revision added a DRY control, adding the ability to add clean boost to the pedal.

 

#3 - The third revision was identical to the production model in its external layout, changing the separate dry & wet controls into a MIX control. A full-signal LEVEL control was added to adjust the post-gain of the entire pedal.

 

#4 - The first production unit added an internal trimpot to adjust the tone of the delay signal. Feedback control is re-named "ECHO" in order to fit on the new silkscreen graphic. Added a charge pump to increase headroom of analog signal path.

 

Here is what is new in the current version:

- Improved taper of the ECHO & SPEED controls, making it much easier to dial in the settings you want

- Added range of LEVEL control, up to 20dB of boost!

- Dual-Mode switching
