Gareth Hughes Posted June 22, 2009 Share Posted June 22, 2009 Hey Folks - Up for sale here is my Barge Concepts GLZ Pedal. It's the perfect pedal for boosting low output pickups, or for boosting your signal into a valve amp or overdrive pedal. The buffering stage is perfect for matching Double Bass piezo pickups into Electric Bass designed pedals/amps etc. The pedal is in perfect nick, having never been gigged or used outside my studio. Brand new these are about £75 with shipping, plus import duty. Get this mint unit for £50 plus postage (bout a fiver). Here's the guff from the Barge Concepts website: The GLZ is Barge Concepts’ all-in-one signal buffering/ clean boosting/ impedance matching solution, built in to a rugged, compact enclosure. Inspired by the buffer and boost stages of the VFB-2 and DB-3, as well as client requests, the GLZ is a low noise, true bypass, opamp-based signal buffer, with 0-15 dB clean boost (Gain control), buffered volume control (Level control), and variable impedance control (Z control). Also available is the BV-1; a simplified implementation of the GLZ, for those that just need a signal buffer and volume control. Application Suggestions: As a Clean Boost: Based on the boost stages of the Barge Concepts DB-3, the GLZ can provide 0 - 15 dB of clean gain. Use it to drive your pedals and amp into distortion, to boost the output of low output vintage wound pickups. or to match output levels when switching between humbucking and single coil instruments. As a Volume control: Based on the topology of the Barge Concepts DB-3, the GLZ's volume circuit is designed to provide variable level control without altering the impedance or frequency response of your output signal. Use the GLZ as a foot-switchable volume control to lower the ouput of your pickups, or use it as a fully buffered master volume control in the effects loop of your favorite amp. As a Signal Buffer: The GZL-1 uses a very low noise, audio grade Burr-Brown non-inverting buffers to insure transparent sound across the entire audible spectrum. With all signals buffered, you have a lower impedance signal driving the devices after the GLZ, as well as high impedance inputs to insure that a clear signal passes to the output. As a passive signal emulator: The GLZ’s variable impedance control alters the resistive output of the buffering stage, to make the output signal appear more like a passive signal. This is particularly useful for bassists and guitarists with active pickups that want to send a 'passive-looking' signal to vintage effects that may not respond well to buffers. GLZ-1 Features: • Compact, aluminum enclosure. Footprint 4.7” x 2.5”. • 3PDT true bypass switching. • Dual color Bypass/Active LED indicator. • Low noise, audio grade Burr Brown op-amps. • Low noise, 1%, metal film resistors used throughout • High quality mica, film, and tantalum capacitors for unmatched signal fidelity. • Switchcraft jacks. • Alpha pots with set-screw knobs. • Clean interior layout with 2 silk-screened and solder-masked circuit boards. • All audio jacks mounted on the North end to save board space. • Industry standard 9V DC power jack (operation supported up to 18V with regulated power supply) • Top quality 9V battery pre-installed.
