Roland Micro Cube Question

SurferJoe46 · #1 10-29-2011, 05:57 PM

On the way to a friend's front yard sale - I dropped at the local swap meet and traded a Roland Micro Cube for a pair of EIDE Phone/Modem expansion cards I've had laying in the bottom of a junk box and were destined to be sold or junked today.

I'm cleaning out junk for the big move to Montana, so a lot of stuff has gotta go! No - NO basses or bass gear!

I didn't want to second guess the guy - we both got fat although somehow I think I got fatter.

Anyway - the Cube runs on my AEB10BEK Ibanez just fine - lots of power for a flyweight amp - amazing!

The Micro Cube didn't have a wall-wart power supply, which I can see is required to be 9VDC.

It runs very well on batteries and that's OK - but I want to know if my 1-Spot can handle the current and since the voltage is correct, I've just gotta watch the polarity.

Any thoughts?

Oh yeah - I also have an extremely stable switching power supply too with the correct jack and all - but it puts out 10VDC.

Whatcha think? Transistors aren't THAT single-minded are they that they ONLY want or require exactly 9VDC?

Not sure about your question, but that pic is the guitar version not the bass version. My .02 is that the features are nice but the tone is mediocre at best. I have bass version.

IME wall-wart type power supplies - even the ones that claim to be regulated - aren't actually that stable. If it was me I'd use the 10Vdc supply without hesitation - 20 years in consumer electronics followed by another 20 with the industrial variety have shown me that many values are nominal. Generally, complex electronics that need extremely precise voltages (to one or two decimal places) have very accurate voltage regulation built into the circuit board. For a simple practice amp I'm sure you'll be fine.

Yeah I know it's for guitar and not bass - I was just asking for the voltage requirements of it. I was carrying my AEB when I had the opportunity to get it, and that's the way I tested it - that's all.

Later I took it home and plugged in a guitar and it's really cute. It's got all kinds-a bells and whistles. And it's very loud too.

So now I'm thinking of a bass version.

Cool. It is really great for guitar but not so much for bass IME. I'm still keeping mine because it has some very useful features such as drum machine and battery power. Could be really cool camping etc.

I lost mine (to the bass microcube), went to the roland site to find out the model # of the adapter, typed it into ebay, and picked a compatible one up for under $5 shipped. Works just dandy, and is a lot less cumbersome than the roland one.

I actually have another intended purpose for it too - my harmonicas. It has a nice dirty sound in that rectifier setting adding in some delay.

Good to know - thanks.

I put the power supply I have on my mini scope and there's not even any ripple in it --- and open, it runs 10.1VDC and on the load of the Micro Cube it shows at 9.2VDC, so I think all's well.
