BAM is a stereo reverb processor inspired by the late 70s / early 80s digital reverberator units.These units are sought after by sound engineers, producers and musicians for their grainy, warm and musical reverberations.
Here at OTO, we are passionated by the technology of the digital reverberators, especially the old models !
We have carefully listened to all digital reverberators built from 1976 to 1986, studied their architecture and read all the available papers (from 1961 to nowadays) on digital reverb design. It seemed obvious to us that the musicality of the early digital reverb processors was partly due to the algorithms (the way the processor synthesized a natural reverberation), but also to their hardware limitations.
The audio signal was severely high-cut filtered (10 kHz was standard at that time) because of the limited sample clock. Some units used 12 bit gain stepping converters to achieve a 15 bit resolution and others used the first 16 bit converters. Then the samples were digitally processed through a 16 to 20 bit fixed-point CPU with limited memory. The algorithms had to be simple but efficient to create the most musical and versatile reverberation from these limitations. And the hardware itself added grain and warmness to the sound.
The technology used in BAM is very close to the one used in these early digital reverberator units : 16 bit converters, 20 bit fixed-point processing, analog filtering and even an input transformer transient simulator. Some of the 7 reverb algorithms are influenced by the early structures, and some are brand new.
BAM is a very musical and unique reverb processor. It combines the sound quality of a vintage reverb processor with the playability of a desktop effect in a compact format with MIDI control and 36 user presets.

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.

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.
