The Keeley ‘Bassist Limiting Amplifier’ is a studio quality Compressor and Limiting Amplifier engineered for Bass! Small and Simple, The Keeley Bassist provides true high-fidelity compression and limiting. Be heard and felt using performance compression by Keeley Engineering!

The Keeley Bassist Limiting Amplifier and Compressor is built around the exotic and extremely high fidelity THAT Corp. 4320. Think of it as very affordable studio-grade compressor in stomp box format! It uses high performance Voltage Controlled Amplifiers, on board true-RMS detector, and ultra high performance op-amps to bring players the very best quality. VCA compressors give players precise control. Therefore they are directly suited to bass guitars. The Keeley Bassist Limiter/Compressor is both musical and very transparent. Where Keeley’s older compressors were based on the CA3080 or the LM13700 and are perfect for single coil guitars, the new Keeley Bassist Limiter/Compressor has no problems with active pre-amps and line level input signals! Not only can the Keeley Bassist handle astonishingly large signals, it has an incredible bandwidth of over 20 KHz and incredibly low noise. No detail in the bass guitar’s tone will be lost. The Keeley Bassist is a sound investment in tone, you now have rack-mount quality at your feet.

When bass players use the Keeley Bassist Compressor they will be greeted with a sound that is more easily amplified and heard. Using the effect as a limiting amplifier saves speakers from clipping and distortion. Set the Threshold to look for peaks in the signal and limit distortion from the amplifier or damage to the speakers. Simply watch the Threshold Indicator light to see what type of playing to limit, it’s that easy! Next set the Compression Ratio Control to determine how much squash happens when the signal is above Threshold. Set Compression all of the way down for no (1:1) compression and use the Gain control as a boost! Set Compression all of the way up for an above-Threshold hard-knee limiter.

A typical soft compressor setting would be 2:1 above threshold. A good starting ratio for the Compression control may be 4:1 as it generally sounds good with bass guitar. A ratio of 5:1 or 6:1 will sound great for slap or funk-style playing. For synth-bass try 10:1 Compression.

There is a certain figure that just sounds good as far as compression goes; and that’s 125 dB/second. With feed forward compressors that use this type of true-RMS detector players use a single time constant parameter. The timing capacitor gives players attack and release times that are adaptive to their playing level or the signal input to the compressor. Bottom line: Attack and Release times vary on program content. Attack times are, generally speaking, about 100 times faster than release times.
