Carl Martin / Classic Optical Envelope / Effect Pedal For Sale
Carl got a call from an old guitar playing friend who said he didn’t want to use his wah all the time, but wanted to have some of those effects available. Enter the Classic Optical Envelope….essentially a classic envelope filter (auto-wah utilizing the same opto-technology as the Opto-compressor) for guitar or bass, with a bunch of cool options. The first footswitch is for fx on/off (buffered), and the second to select between the three modes (High Pass, Band Pass and Low Pass). Add to this the Level control for overall volume, Drive for how hard the auto-wah will function, Q for adjusting the size of the bandwidth, and Tone which acts as a separate Hi-pass filter, and you have complete control over your fx…from vocal like tones to funky quacks and fat wows! Housed in the cool new diecast housing with mini-knobs and cool retro colour, the Classic Optical Envelope can be powered by a 9v battery, but we always recommend a regulated power supply for optimum response!

Carl Martin Company Profile
ESR was founded in 1990 as a professional PA sound rental company. Shortly after we began producing custom made audio equipment.
Our goal was from the very beginning to develop and produce products for the demanding professional musician, with a superior sound quality and features not seen on any other guitar effect pedal. As a result of that our first guitar effect pedal, The Hot Drive'n Boost, was introduced in 1993.
Due to our extensive knowledge of the professional music industry, and our contacts with a wide range of demanding musicians, we have been able to maintain a high quality of products and now have a range of 28 high quality guitar effect pedals, with more to come in the future.
In 2005 we released our first point point handmade tube amplifier the Custom Shop 50, the line now includes heads,- caps as well as a bass system.
