Now, to move on from my sales pitch, let's talk reality. This is a PASSIVE / Non-Reactive speaker attenuator! At anything other than wide open, 100% volume, speaker is not a true reactive load on the amplifier. That being said, ANY passive speaker attenuator should not sound and feel as good as an active attenuator with a reactive load (i.e... Weber Mass/Mini MASS). Especially at critical recording volumes in the 100db - 115db (at Speaker) volumes. While my passive attenuator does sound fantastic at these volumes, simple things like feedback from the amplifier does not propagate as it would without a static/passive load between the amp and speaker.
While the passive load is rated at 100W RMS/200W Peak(65W), 125W RMS/250W Peak(75W), and 150W RMS/300W Peak(85W). I do not recommend use at high attenuation levels and extended periods of time with Amplifiers over 65, 75, or 85 Watts respectively. This allows for some headroom for sufficient cooling and component longevity. With all of this being said, if you are looking for the perfect low volume recording situation for your current stage rig, I would spend the $200+ on a Weber Reactive load attenuator. The Physics behind Ted's design is solid and well worth the $$ they garner. However, if you are looking for the BEST sounding passive attenuator for low volume practice/rehearsal and writing/recording demo tracks, or to tame your stage volume, look no further!
Disclaimer: The attenuator must be connected between the amp and speaker using the proper jacks (i.e... Amp jack(Red) goes to Amplifier Output and Speaker jack(Black) goes to the Speaker). While holding the attenuator with the volume knob facing you and the jacks toward the top, the amp input is to the left and the speaker output to the right. Connecting the attenuator in reverse can seriously damage your Amplifiers output transformer! DON'T DO IT! I will not accept responsibility for any damage associated with not following the included instructions for safe and reliable use. YOU HAVE BEEN WARNED!
