i was within INCHES of buying the RC-30, and then I read this...(lifted wholesale from another forum)
for the loopers - very dissapointed with new BOSS RC-30 Loop Station
I have been holding out for this pedal for so long, still thrashing my RC-20XL 4 times a week out at gigs, and to be honest I'm completely let down by the new RC-30. For the record I use the pedal as a solo acoustic artist/singer, and in a duo with a drummer to lay down rythms/lead parts/bass lines/textures in real time, as part of the live show playing everything from Dylan to Dire Straits to The Doors (see what i did there? ).
All of the cool possibilities that i thought would have been incorporated with the ability to record 2 separate loops (e.g having them 2 different lengths, being able to A/B from one loop to the next for a verse/chorus scenario) have not come through, to the point where, nothing much has REALLY been added, that you couldn't already do with a bit of a brain on the old pedal.
The effects section is largely un-usable (no adjustable parameters, weird choice of effects to start with), phantom powered XLR is cool, but again, not applicable for the way I use the pedal, and hard to use for a solo performer, without completely stopping playing whatever instrument you're using.
The thing which made me return the pedal the same day i bought it though, is that there seems to be no way of setting the 'STOP mode' (immediate/fade/or at end of phrase) on a non-saved loop. I NEVER SAVE LOOPS, i only use it for on the fly live performance, and the first thing I do when the pedal turns on at a gig, is change the mode to 'END OF LOOP' freeing up a little bit of tap dancing while i'm singing. They literally TOOK AWAY this feature!
So with my test, this pedal actually came up WORSE than my RC-20, which i will continue to use, despite the annoying millisecond delay between finishing recording and playback of the loop.
I have never understood why someone would need 99 presets!! Just give me something that can be used in a live environment, and fits the needs of regular gigging musicians. Why would anyone need 'Bend Down/Step Phaser/Sweep Filter' effects? How about a Delay that you can change the parameters, or a chorus/reverb.
To end my rant, I am happy, even hoping, to be proved wrong on some of the above points, I thought that my test was pretty thorough, I found the manual overly simplistic, and the unit had almost none of the 'tweak-ability' that i had expected from a unit with this much potential. I don't think that I am too fussy with my loop pedals, as I have put up with the limitations of the RC-20 (tone suck, glitch between end of record and start of loop playback) since i got it...
END OF RANT, THOUGHTS/COMMENTS WELCOME
THANKS FOR READING AND MAY THE ROCK ON!
