Track your note. The pedal recognizes two or three-note chords and trigger the lowest note. Control the level of the original tone and mix in the octave effect. Choose between High, Mid or Low Range - which relates to the character of the sound of the sub-note.


Hints. Sub-notes are perhaps most effective when playing on the higher frets, and could add a nice touch just slightly blended into the original tone, especially on a solo on bass or guitar. The OctaBass works really good together with distortion as well, but remember to keep the OctaBass before the drive in the signal chain, so it get’s as clean as possible tone to trigger. If you are after a synth-bass type of sound, a great way to achieve that is to run an OctaBass, combined with an EBS BassIQ envelope filter, and use the ‘Down’mode on the IQ. That makes the impression of hitting a key on a keyboard, and adds that sub-bass as well as synth sound to the tone.


The original EBS effect! The OctaBass was the very first stompbox effect from EBS. This classic effect was introduced in 1992, and based on an onboard effect featured in the legacy EBS Taurus combo. It has become 'classic' after being a trusted companion to legendary bassists like Tony Levin, Roger Glover, Tal Wilkenfeld & many many more...


The Studio Edition comes with optimized signal path, new design, new signal relay switching technique, protection against overvoltage use up to 18V and the possibility to power the pedal with anything from 9-12V DC.




Ps. Tricks that apply to all analog octave pedals to maximize performance:


Octave effects are most commonly used to fatten notes played higher up on the fretboard for fastest possible tracking.

If you experience any glitches (or loses the subnote shortly after you play a note) anywhere on the fretboard, learn where these spots are and play the same note on a different position on the fretboard and tracking should be fine. Analog octave effects all suffers from that, although the spots can appear on different positions depending on the model and instrument you use.

For cleanest possible tracking; put octave effects first in the chain of pedals.

To further improve tracking, passive instruments or passive mode on an active bass can sometimes improve tracking.

Other tricks that can be useful if you experience tracking issues with an octave effect is to roll of the highs with the tone control; to roll off the bridge pickup on a Jazz bass when using octave effect; and to play a little softer than usual to avoid that the strings hit frets or pickups in a way that produce unwanted overtones that can mess with the tracking.  

On the other hand, analog octave filters are fun to play with and usually sounds fatter than any digital octave effect.

CITES regulations concerning the export of items containing certain woods affect any guitar sold ouside of the European Union and which contains any quantity of either Rosewood or Bubinga.  In these cases, an additional charge of £80.00 will be levied per species after the sale to pay for the required re-export certificate.  There will be a delay in dispatching any guitar containing either Bubinga or Rosewood of up to 4 weeks while we obtain the necessary certification for export. As the charge is per species, where a guitar contains both Bubinga AND Rosewood, the charge is doubled to £160.00.  We will contact you following your purchase of any guitar containing a controlled wood and advise of the charge once you have placed the order.  You can make payment for the charge by sending a Paypal payment to us at: sales@fxpedal.co.uk. 

Note that CITES only applies to guitars containing Rosewood or Bubinga that are being exported outside the European Union.  Guitars being delivered with the United Kingdom or in the European Union will be dispatched as normal.
