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).
Technical specifications:
- Module width: 14HP
- Module depth: 32mm behind 2mm aluminium front panel
- Current consumption: 62mA on +12V, 55mA on -12V
How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK, 'next working day' shipping is free if the order value is over £150, and £5 otherwise. We can also ship on a 'next working day before 12pm' service, which costs £6 for orders over £150 and £7.50 for orders under £150.
Shipping to mainland EU typically costs between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of DPD, Royal Mail and Parcelforce for the UK, and for international orders it's either DHL, FedEx, UPS, Royal Mail or Parcelforce depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we aim to dispatch the same working day if we get the order before 16:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes the couriers may come to collect a little earlier than scheduled which would also push an order into the next day.
Saturday/Sunday shipping
If you're in the UK and you order before 16:00 on a Friday then we can send something for a Saturday or Sunday delivery with DPD. This is FREE for order values over £350, £5 for order values between £75 and £250, and £7 for order values under £75. (NB: this applies to UK mainland addresses only). Please note that any orders placed after 16:00 on a Friday will ship on the Monday.
International shipping times
Since April 2020, the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer. There is absolutely nothing we can do about this, unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
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 if you have questions.
