The VT1-Bass-Compressor from DHA is a hand built valve/tube Bass guitar optical compressor effects pedal which uses a 12AX7 (ECC83) preamp valve to provide true valve tone.

The tone is fat without any any loss of bottom end but still keeping the mids and highs and no compression fizz. There are 2 modes of compression, hard and soft which are selected via a switch. Soft compression is a low level compression and provides a vintage type valve/tube effect. Hard compression is much more modern sound suitable for slap bass, it also acts as a limiter at higher settings.

The controls are i/p pad, Compression, Decay, Level, by-pass and hard/soft switch. There is an effect on LED, power on backlight which can be seen via the valve vents and compression LED. The compression LED pulses which the amount of compression and decay set.

i/p pad sets the amount of signal into the effect, compression sets the amount of compression in both hard and soft modes. Decay sets the decay level of zero to long levels and hence the smoothness. Level is the output level control.

The circuit uses a 12AX7 (ECC83) pre-amp valve in the signal path and 2 types of optical interface for the hard and soft modes. 5 high quality dual op-amps (10 stages) are used for peak detection, decay and signal boost. There is a lot in this little box!

It has taken almost a year to develop this pedal working with pro and semi-pro players in order to provide an effect that is right for all bass players.

The VT1-Bass-Compressor runs from a 9-12VDC 500mA (12VDC 1200mA recommended) supply via a standard 2.1mm socket. ( A suitable PSU can be supplied at an additional cost of £15.99 (UK only) if required, just add this to cost of your purchase.)

The VT1 -Bass-Compressor is totally hand built using a quality PCB and point to point methods, even the box is hand painted. There is a one year return to manufacturer guarantee which covers parts and labour in case of failure with each unit. There is also a user manual.

I will post World wide, but please check first for a price outside of the UK. As it runs from a standard 9-12VDC supply there is not problem with using this item anywhere in the world.

PayPal is the only excepted method of payment outside of the UK.

The VT1-Bass-Compressor offers great value for money as it offers valve/tube optical compression normally only found in high end studio rack units.

Watch out for our DHA 1U rack version Dual/Stereo Bass Compressor coming soon.
