About a month ago I was set in my tube/OD department and looking to expand my fuzz-verse and maybe pickup a phaser (while always scoping out Bongo's compressor reviews because one of those is always on my back burner). I put a pedal up in the classifieds and asked for trade offers. Someone offered me the Swell B-TOD V1. I haven't looked back....for this entire month. I wouldn't consider myself a veteran of ODs. I've had a GT10-B, a Sansamp BDDI, and the only tube/OD I've had was my B3K. Others on this forum would look at someone with 20 of these guys under their belt and call them a noob. So I'm not pretending to be an expert. Just passing on my opinion. To give a brief overview, Swell is a small company based in Nashville that I have no affiliation with (and get no discounts from). The name is a bit unfortunate in that if I started a thread titled "Swell B-TOD", a lot of people would think I was trying to pimp some sort pansy swell pedal (nothing could be further from the truth) and quickly pass over it. Their vacuum tube pedals are the "union of classic tube technology coupled with innovative circuit designs". They have two footswitches on the pedals giving you the flexibility to switch between two different gain levels without having to bend over and mess with stuff. Bass-wise, they offer three types of tube/OD pedals; The B-TOD (high gain), B-PRO (mid gain), and the B-DRIVE (low gain). They also have a bass boost pedal. The newer versions have FAT and CUT switches to further help shape the tone but the one I have doesn't have them...so I can't attest to them. Anyways, getting to it, I got this thing in expecting to try to flip it for a profit and it's kicked all other ODs off my board and I'm now saving to get a new model. I use a custom Status Graphite bass and play through an Eden Nemesis head and a full on Eden stack with 115 and 410 cabs. So my clean tone is pristine crystal clear solid stateness. The B-TOD completely takes that sound and transforms it into a vintage tube amp. Other pedals compared to the Swell are like gold coating on a nickel ring. The B-TOD is like alchemy. Totally changes the sound with no trace of the solid state in there. And it has a ton of gain. To be honest, it's a bit too much gain for my taste, and when I buy a new one I'll be looking at the B-PRO. But for those looking to get so much gain it goes into fuzz territories, the B-TOD is the beast for you. It surprises me how quiet it is when not playing. I'm used to pedals with this much grit and dirt being noisier. I didn't notice a thing and with my rig, it's pretty easy to notice the slightest bit of buzzing. The thing I love is that it works great with active and passive basses. My pickups are active and very hot...so I've been having to deal a lot with pedals that aren't friendly with my guy. I know that's a lot of dough to throw on a pedal. And usually when it gets that high, I need a lot of reviews to get me to even start considering looking at something. Well here's one. I sent my B-TOD out on a little minitour. Those people will hopefully give some reviews and they're more experienced than me. Once it gets back, I'm flipping it to fund a new Swell B-PRO V3. PM me if you want to give the V1 a try before I flip it....I would love to send it to whomever wants to try it out....but I'm also anxious to get the tour done so I can buy a new one. But let me know and I'll see if I can get it out to you. Again, I'm not affiliated with Swell in any way. I'm just extremely grateful for everything this forum has done for my sound and want to give a little back. I also want to give a little hype to a company that hasn't gotten much but deserves to get a lot more....well...they won "Best of Show" at NAMM...so they DO get hype. Just not much in the forums I frequent. EDIT...here's a video of all three bass pedals in action that gets added on page 2.
