Basswitch IQ DI Review by Eric Parsons
I want to focus first on the switches in this unit. I don’t normally get excited about a foot activated switch, but these deserve some special recognition due to their design and performance. The Basswitch IQ DI does not rely on a typical stomp box button and instead utilizes a mushroom shaped button that is mechanically and electrically isolated from the internal circuit board. This design reportedly lengthens the lifecycle of the switch as well as improving the quality of the electrical signal. Lehle claims that this approach will allow for each switch to have a lifecycle of 2 million clicks, as compared to twenty thousand for your garden variety stomp box. More importantly, these switches are dead silent in their operation with no pops or clicks when activated. There are three of these foot switches on the unit for the following functions (1) an A/B selector to toggle between the two inputs, (2) a mute button and (3) a mix loop/boost button.
The Basswitch has two effect loops: a passive serial loop and a switchable infinitely variable mixing loop. If you have effects that are continually in use, these would likely be placed in the serial loop. Effects that are used intermittently or that require more control over their mix would more likely be placed in the mix loop. For example: I placed an analog chorus and an analog delay in the mix loop and then mixed in about 50% effected signal with 50% of the original signal to help retain a little more bottom end to the sound. I could then bring both effects in and out with the single switch. If no effects are placed in the mix loop, the switch can then function as a clean boost. The mix loop also has a polarity switch to invert the phase if the two mixed signals sound thin together.
The Basswitch also has a balanced (XLR) DI to connect to a mixing desk. There is a ground button (to eliminate hum, a pad button to attenuate the signal if only microphone inputs are available and a pre/post switch to allow for an effects free signal to go to the board – if that is preferred.
The Basswitch also has a tuner output jack.
I have not described the external power supply, because one is not provided. I thought this a little odd at first and contacted the distributer only to find out that the Basswitch has been designed to accept virtually any power supply (provided that the jack is correct) that will provide any voltage between 9 and 20 volts with a minimum of 130 mA. I had at least 5 wall warts in my closet that would fit the bill – so this was a nonissue.
In Use
I took the Basswitch, a power amp and a speaker box to medium sized event where I would be playing both my fretted and fretless five strings. I ran the fretless through input A, with the preamp and EQ, and was able to quickly dial up a very nice sound. I ran my fretted bass into an Eden WTDI pedal and then into Input B (which bypasses the preamp and EQ sections). I was a little concerned that I might overload the input of the B channel with the WTDI, but found that the Basswitch could readily handle this signal chain with no audible distortion. This setup gave me all the flexibility I could ask for. I dialed in the EQ on the fretless to just get that slight growl that I like and the fretted bass through the WTDI allowed me to use the built-in enhancer and compressor to get a nice fat slap sound with just enough top end sizzle to give it some snap.
In closing, I would like to thank Dana B. Goods, Musical Instrument Distributor, for providing the Basswitch IQ DI for this review.
