Manufacturer's description
Explorations around a schematic found among old papers of mysterious origin, suspiciously similar to a datasheet sq/tri oscillator. All that was needed was to connect the dots.
Slew limiter core
A slew limiter smoothes out how quickly incoming voltage can change, limiting it to a fixed v/sec. slope. since time and frequency are intrinsically linked, this acts as a steep, somewhat distorted low pass filter.
When it resonates (FEED), these fixed slopes become triangle wave oscillations, giving 20% more its unique sound. Your input signal can overwhelm this oscillation, making for pseudo-wavefolding and synthetic distortion artifacts.
This topology can result in quite a dark sound when SLEW is low, as there will not be much harmonic content present beyond the cutoff frequency. You can use BLEND to mix in a square wave signal that can help bring back some higher harmonics.
Low pass gate
20% More has a slightly resonant, 2 pole, 12dB/oct low pass filter at it's output. It offers a nice counterbalance to the grit of the slew limiter, and allows tasteful reigning in of the crackling potential present in the circuit.
Envelope follower
There is a simple internal envelope, its main purpose is to allow high feedback settings while avoiding (possibly unwanted) oscillations when no input is present. Both envelope destinations achieve this through different means.
When the envelope goes to the LPG, it is a bit like a sidechain input, where your playing dynamics open up the filter and let highs pass through, giving some nice springy west coast bongos; the LPG knob needs to be set low for the gating to be effective.
When the envelope goes to FEED, the average feedback is lowered slightly, loud playing will bring it back up. As loud inputs also fight the oscillations, interesting swashes of noise arise as your notes decay.
Play with INPUT. Interactions become intuitive.
Sub octave
20% More can route a squared version of the signal to one or two filp-fiop based clock dividers, giving sub-octave and sub-sub-octave effects. It is only heard when BLEND is up somewhat. The sub octave is summed through diodes, giving it a characteristic 75% pulse.
Full wave rectifier
Envelope following requires a strictly positive input voltage. To achieve this, a full wave rectifier circuit is used. It is repurposed in the audio path as a switchable octave up. This particular implementation squishes very hard when INPUT is beyond noon. Enjoy.
Controls
- INPUT: 'mu amp' jfet preamp, lots of gain
- BLEND: mixes in a square wave / sub-octave copy of the signal
- VOLUME: output volume, gets very loud
- SLEW: slew limiter frequency
- FEED: slew limiter feedback
- LPG: low pass filter
- D - OCTAVE DOWN: clock division of the blended square wave, -1 or -2 oct
- U - OCTAVE UP: analog octave up, full wave rectifier
- E - ENVELOPE DESTINATION: routing of the internal envelope; either added to the (L)PG or (F)EED controls
Internal controls
There are two user adjustable trimpots inside the pedal; they are labeled TR3 (drive) and TR2 (sens). The two other trimmers set the jfet bias and v/oct calibration, they should not be adjusted by the user.
- DRIVE: Sets the amount of signal going into the JFET clipping stage, another 20% more?
- SENS(ITIVITY): Sets the gain of the internal envelope, allowing you to attenuate or exaggerate the response to your playing dynamics.
- Dimensions: 4. 7" X 3.8" X 1.9"
- CV input range: 0 - 5v normal ; 0 - 8v max 9VDC
- Power supply: 20 mA@ 9.6 VDC
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.
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 and Royal Mail for the UK, and for international orders it's either DPD, DHL, FedEx, UPS or Royal Mail 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 normally 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 delivery
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
Most orders are delivered within 3 to 5 working days if sent on a courier service. Royal Mail services can take a lot longer and are often less secure.
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.
