As promised, here is my review of the EBS Microbass II. I’ve had it now for a couple of months so I’m finally comfortable giving my opinions on it. First off, this was an impulse purchase for me. I really didn’t need it as I already own a SansAmp BDDI, but have been lusting after one since I read a review about it in BP a few years back, I just couldn’t justify the price. Luckily another TB’er, Timothy was able to get one for me from a dealer in HK for an incredible price. Construction: The construction is on par with what you’d expect for a good stomp box. Heavy, solid, with high quality footswitches and input/output jacks, and smooth knobs with center detents where applicable. One very nice touch is that it has a door for easy access to the 9v battery. The door is also of pretty high quality, better than those on most basses I’ve seen. It’s about 1/4 larger than my SABDDI, and noticeably heavier too (it weighs in at about 2lbs). My only concern is that it has several “chicklet” style buttons both on top (sandwiched between the knobs) and on the sides between the ¼” jacks. I’m not so worried about the ones between the knobs, but the ones on the side stick out and could possibly be damaged with rough handling. As far as battery life goes, all I can say is that I've been using it quite regularily (particulary as a headphone amp) since I've purchased it in March, and I haven't needed to replace the battery yet Features: This is the “swiss army knife” of pedals. It’s a footswitchable full featured two channel preamp with separate inputs and LEDs for each channel (you can even sum the two channels in series if you’d like)… It’s a DI box with speaker simulation… It’s a hi-fi headphone amp… It’s got distortion and tube simulation… It’s got a send/return section with full wet/dry mix… Mute footswitch… All this and it can run off of a single 9volt battery, what’s not to love! The only things missing that I would have like to seen is a pre/post EQ switch for the XLR out and a separate volume control for both the XLR and the instrument out. Versatility: It should be obvious from the list of features that it’s extremely versatile, but how can one use it? My main setup is: Peavey Cirri (I have both a fiver and a sixer) --> GK-1001 II --> Schroeder 1210. Under normal circumstances, between the Cirrus' & GK's flexible preamps/DI, I don't feel the need to use the Microbass for additional tone shaping with this setup. However, here's how I’ve been using mine: I’ve been keeping it in my gigbag as a backup tool so I can run directly into the PA should I have a problem with my amp. If I bring my Lightwave fretless, I'll run the GK flat and use it as a dual channel preamp so I have both basses plugged in. A step of a footswitch is all I need to do to switch between the two basses. It's especially nice to be able to have each channel's EQ controls setup specific to the bass that's going through it. I use it with headphones for silent practice while watching TV with the wife, and sometime play along with the television music scores and commercial jingles. I'll also connect my MP3 player via the effects return to jam along with tunes. During practice and coffee house gigs, I’ve been using it to beef up the bottom end and give some "oomph" to my little Fender Bassman 25. Sound: Here’s where it gets subjective, but I’ll do my best to describe what I’m hearing. Channel A: There are three knobs (Treble, Bass, Boost) and two switches (Bright, Enhance Filter) that apply to this channel. With everything set flat and the tube sim & bright switches disabled, it sounds pretty transparent to me. The bass control is adds/subtracts up to 15db at 100hz. By itself, 100hz would be a little high for my tastes, but with the GK’s bass control at 60Hz, the Bassman 25 at 80hz, and the Cirrus at 120hz, it works out pretty well. The treble control (+/- 12db @ 10kHz) is kind of interesting… with the “Enhance Filter” switch enabled, it functions similarly to the SansAmp. Turning up the treble scoops the mids, while backing off on it raises the mids. With the enhance filter disabled, it functions as normal. There’s also a “Bright” switch that when enabled, gives an additional 12db of boost at 10kHz, adding some sheen and sparkle to your tone. Finally, there’s a “Boost” knob that serves as a preamp gain for this channel. This control is also how you set your channel A level to match that of channel B (depending on how high you set the “Drive” level on that channel). My impression of this channel is that it has a “Hi Fi” sound… Clean, crisp, and studio quiet. Channel B: There are four knobs that control this channel (Drive, Edge, Middle, Mid Freq). The “Drive” knob is how you add some grit to your sound (it also raises the volume of this channel as it's increased). the grit starts getting noticible around 9 o’clock and starts getting nasty (which can be taken as good or bad) once you get past 12 o’clock. I prefer somewhere around 10 – 11 o’clock, which gives a nice subtle tube overdriven sound. This is a good time to mention the “Tube Sim” switch which supposedly adds some “tubey goodness” to the mix. In most cases I seem to prefer it disabled. It makes a subtle difference (unlike the blend knob on the SansAmp) by rolling off the highs a bit. Next is the “Edge” control, which adds/subtracts up to 12db at 7kHz. This control seems to work hand in hand with the drive knob to let you go from creamy overdrive to buzz saw distortion. I find myself leaving it flat in most cases. Last but not least, there’s the semi-para mid control. +/- 12db sweepable from 50Hz through 2kHz (fixed Q at .80). This is the channel for achieving that overdriven SVT sound. I think I prefer the SansAmp for this use as the tube sim & overdrive on the SABDDI seems smoother to my ears, but honestily, I don’t go for that sound often and I haven’t played around with all of the controls on this channel to get a real good feel for how they interact with each other. Overall Impression: Personally, I think this is an amazing piece of equipment. To stuff all of this functionality into a battery powered stompbox is simply incredible. Add to that the ruggedness and studio quality sound, it makes for a killer package… Plus it can function as a headphone amp!!! Would I have paid full price for it? Probably not, but now that I have it I’d be hard pressed to give it up. BTW, I’m still keeping my SansAmp (it’s too good of a tool to get rid of), but it’s been moved to my other gigbag (at least for now) http://www.bass.se/koll/MicroBassII.htm - Ugly.
