The Gristleizer Pre-Amplifier is a new addition to the existing circuity of Roy Gwinn's "Guitar Effects Pedal" design. After Chris Carter's suggestion of a guitar pre-amplifier for use with the rest of the Gristleizer series, the TG5 came into being. Based upon Jonny Reckless' FET-based discrete amplifier circuitry, Roy Gwinn has designed a pre-amplifier with a high quality VCA back-end which allows for any external audio source to become fully integrated into a Eurorack system.
The Guitar or Line input is firstly fed through one FET stage of the pre-amplifier, and then into a super-clean THAT VCA, the direct output of which is available at the Clean output. This source is then fed through two more FET amplification stages and a tone section (featuring the typical Bass, Mid and Treble controls found on many guitar amps) to the Master output. Bite and Boost controls allow for further control over the tone of the input signal.
An RMS detector (found as part of the THAT VCA) is employed as an envelope follower, as well as a gate detector. The Sensitivity control allows the user to set how the RMS detector reacts to the incoming signal's level. Access to the THAT VCA's Gain control input allows the two Envelope outputs to be used as control sources for the pre-amplifier itself, turning the module into a dynamic compressor (Inverted Envelope) or expander (Normal Envelope).

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
