    Hey friends,

    Just got this pedal and it sounds phenomenal. Anybody else have one?
    Here I am playing it in this video:

    That is with pretty light effects on. It can get much richer if you want it to.

    My question is about "bass mode". The pedal offers a guitar and bass mode. It comes standard in guitar mode, and I'd like to switch it to bass.
    But it isn't just a simple switch. I need to unscrew the back and tinker around with it inside to adjust. It sounds fairly simple, but I am a bit nervous to do it (I don't want to mess the pedal up in any way). Does anyone have any advice for doing pedal surgery?
    Thanks for your help!

    Don’t sweat it, this sort of thing is really elementary. Undo four screws. I would imagine it’s just the flip of a tiny dipswitch or two, use the end of a small flathead screw driver to do that if need be. The manual probably has very clear instructions or a diagram for setting switches.

    if ur really still nervous, contact Keeley, they’re good people, u’ll get help...

    I have one. Super simple to flip the bass mode on. Makes it a little more lush, and bass friendly. I tgrow it after my reverbs to add some ambient space to the trails. Also works great on its own for a little extra to your bass tone.

    Question for you Seafoam+ users- Is there any kind of volume drop when the pedal is engaged? I just got an Ampeg Liquifier, and the sound is fantastic, but the volume drop is pretty drastic. I really wanted an analog chorus, but that Keeley Seafoam+ sounds exactly like a chorus pedal should sound!

    @mikeguyfriend - Nice playing!:thumbsup:

    Have you tried putting another pedal after it?
    I have an MXR Phase 90 'Script' version, and I get a noticeable volume if it's the last pedal in the chain, but there is no volume drop if I put another pedal after it. Try it, maybe it'll solve your problem.

    I'll give this a shot, but it doesn't really help my situation. I generally run all my modulation thru my amp's fx loop. If I run it there, which is where I prefer to run it, there's no volume drop and it sounds great, but it is, literally, one of the noisiest pedals I've ever had. If I move it to the "straight in" part of my board, there's no noise, but that crazy volume drop. I had read that in another thread. I'd hoped that guy got a bad one or was doing something wrong. Turns out he was dead on. I will experiment with another pedal behind it, just to see what happens, but I'm 99% sure the Ampeg is going back. Thanks for the tip!

    I just gotta find a Keeley, because Sweetwater is, of course, out of stock atm...

    Thank you for the kind words!
    I have not noticed any kind of volume drop when I engage the pedal. Sounds great!

    I'm on a continuous hunt for the perfect chorus and found that this Seafoam Plus is really great sounding. I opened it and put it into bass mode for the first week, which has 3 alternate modes including a flanger. Two nights ago I reverted it back to the default (guitar?) mode and right now i think i prefer it vs the bass mode. Not a huge difference in tone, just the functionality, one setting has a reverb that you can add to your chorus voicing. Just a little goes a long way. The quality is great, and to the OP, it's super easy, other than the philips head screwdriver to open the thing, you can flip the small switch with your finger.

    Going to try Vintage mode next, does anyone have experience with that?

    I think I prefer the guitar(?) mode as well!I did switch to the bass mode, which is great too, but the guitar mode features suite my playing a bit better (and it all sounds great through bass...they may want to reconsider how they label these).
    Did you try vintage mode? Curious how that sounds

    Hi all thanks for the kind words with this pedal. I am a little late to the convo here but setting it to bass mode will change the eq freqs and make it more bass friendly. It is super easy, pop the back plate off and you will see two little switches. Flip them to the corresponding direction in the user manual then pop the back plate back on. If you mess it up, break and switch or anything happens out of the ordinary feel free to email me at [email protected] and I will get you back up and running and set in which ever mode you prefer before sending it back.

    I just got this pedal today, and did a quick try out. I am amazed already at how awesome the sound of this chorus is. Have tried and used a lot of different chorus pedals over the years, for guitar and woodwinds as well as now primarily bass. This is simply an amazing, lush and beautiful sounding pedal. I never say words (anymore) like this is the last (name the effect here) pedal I will buy because I seem to always be on the lookout for new things, but I definitely don't see this going anywhere. Thanks Keeley!
