Partially agree. Let the guitar be the guitar and not keys.
But, the leslie organ sounds have creeped into guitarists heads and stuck. Lot's of vibrato, chorus, rotary speaker, etc. efx. are part of the guitar bag now.
So the exception for me would be the leslie / organ sims. These are in the guitar bag. And this pedal is pretty cool for that.
Totally agree with you that certain organ effects have become popular, and rightly so, as using a rotary speaker sounds great with a guitar coming through it. This pedal though isn't so much a rotary sim, as its supposed to sound like an actual organ, which it does pretty well. Certainly the best to date.
Thing is though that its kind of a cliche organ sound, opposed to a real rocking Hammond organ ala classic rock tracks. If you wanted to do some cheesey 7th inning stretch mascot dance sounds like at a baseball game it works great for that. If you want to play some fast "Phantom of the Opera" style cathedral organ piece, its great for that. Can pull off some nice cheesey transistor organ tones too.
Just how useful are those type of sounds in most music though ? Once you get past the 30 second "whoa cool, his guitar is making organ sounds" aspect, are you really going to stop being a guitar player and do organ parts on multiple songs ? Which if so, perhaps would suggest, at least to me, that you should get a real keyboard, and/or an extra band member who plays keys.
Its actually gotten very easy for even non keyboard players to play keys these days. My Native Instruments software has a chord mode where you can select 5th, 4th's, 7th etc and you just need to press one key to play proper chords. It also has a scale mode where all the notes that trigger are in a proper scale, say a blues scale, so you literally can't hit a wrong note.
I mean if someone enjoys the pedal and has fun with it, that is great, I'm not trying to dampened anyone's fun, but, at the same time, I do think its just that, more "fun", than it is a way to make up for having a keyboard player in the band.
Other thing is that these sounds can become over used really quickly. Remember when everyone had the EHX POG ? I had one too. Made some pretty unique sounds, but then Jack White did "Blur Orchid" with it, and then pretty much everytime I used the thing, people thought I was trying to do that track, or go after his tone. Gets to the point where its hard to do something unique, because its such a unique sound that always gets associated with that track. As such, my $350 pedal became one I didn't really want to use much, because I wasn't doing White Strips covers.
I'm not saying there is anything wrong with wanting gear that gets a certain artist sound though. I got a reverse wah, ala David Gilmour, for the exact reason I wanted to make David Gilmour "seagull" sounds. Could I try to break that out during a set though and have it sound like anything BUT a David Gilmour tone ? No way (unless maybe the audience is 15 and never heard of Pink Floyd lol). Point being, its an iconic sound from a reverse wah, with one particular track.
Stuff simply gets overused, "shimmer" reverb for example. Awesome at first, but then when 2 bands that went on before you that night both had songs that featured the effect, is it still as cool as when you first got it ? Now its become a parody of itself almost.
I think hundreds of kids (and adults) are buying the B9 at GC every day, and as it is cool for what it is, we are going to start seeing more and more of them used during bands sets. It likely will get to the point where its become overused and gimmicky, and then we'll see tons of them hitting the used market.
Just like the POG, or the Whammy etc. I bought all those pedals when they were hot, and ended up selling them for pretty big losses once they were not.
