EBS Microbass II Preamp/Di

This is the ultimate bass tool. Period! The MicroBassII can be used as an active direct box, a one or two channel preamp, instrument switcher or blender.

Two Channels and A Useful Loop
The two channels provide sound shaping from high end solid-state types to distorted timbres, using the awarded tube emulation circuitry found in the EBS range of professional bass heads. An incorporated effects loop gives the user added flexibility for connecting to other effect pedals, or for mixing in an external audio source such as a CD player for rehearsal purposes.

Unmatched Flexibility
The balanced output with speaker simulator option provides unmatched flexibility in live and studio situations. Footswitches control mute and channel operation/switching.
Other features include headphone output, low battery indicator, link and master outputs, bass, ‘sweepable’ midrange, treble, bright and edge filters, drive and effects mix controls. The EBS MicroBassII delivers that big, burning EBS sound wherever you go.

MXR Bass Preamp

The MXR Bass Preamp combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedalboard space. Use it to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. Dial it in just the way you want it and send it straight to the house—pre or post-EQ—with the built-in Direct Out.

The Bass Preamp features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange—from 250hz to 1khz—for extensive tonal flexibility. It’s all delivered super clean with high headroom thanks to our own Constant Headroom Technology™, and you can use the PRE/POST EQ switch to set whether or not your Direct Out signal is affected by the Bass Preamp’s EQ section. And of course, the Bass Preamp features a GROUND LIFT switch in case you encounter ground loop hum.

The Bass Preamp is factory preset to operate in ¼” out buffered bypass and Direct Out active. For players who only want to use the ¼” out, there are two internal switches that disable the Direct Out and ¼” out buffered bypass for true ¼” out bypass mode.

MXR Bass D.I.+

Finally, all the essentials in one tough little box. You need a serious D.I. for playing live and laying down killer tracks. You've got to have a preamp and finely tuned EQ to add punch to your tones. And you definitely can't do without some rich, custom distortion. This one-of-a-kind pedal gives you the whole deal in a bomb-proof enclosure that will survive even the most out of control gigs-and players. Built with the highest quality components, the M-80 can give you eve everything from warmth and transparency to a volcanic roar, without making you scroll through menu screens or an indecipherable manual. Engage the color switch for some sweet preset EQ, then tweak your tone with three band control. Dial in your ideal distortion with the gain knob and blend just the right amount into your clean signal, then kick it on and off at will. The adjustable noise gate pours on the sustain and cuts out hum and hiss. With XLR and parallel 1/4" outputs and a phantom power switch, you'll never have a problem delivering your choice new tones. Power: Single 9 volt battery or Dunlop ECB003 AC Adapter
