On Tone Suck
On 'Tone Suck'
People talk about tone suck. Usually this is in the context of what a pedal does when it's turned off... and the alternative is usually rendered as "true bypass," which is when an 'off' pedal lets the signal through without doing anything to it. All of that makes perfect sense, but there's more to it than that.
I've been through a few famous pedals, and to my ear, they all 'suck' in one way or another, and I don't necessarily mean when they're turned off. The first one I thought this about was my Ibanez Tube Screamer in the context of my Vox AC15. The Tube Screamer does a relatively sophisticated overdrive thing with a mid-frequency bump which helps solos cut through the mix. Allegedly, the Tube Screamer pushes the mid frequencies that are missing in a blackface Fender amp (the ones they took out of Tweed amps to get them to stop distorting). But in the Vox, which is already hot in the upper mids, the Tube Screamer pushes mids on mids, and it trashes the high end, which is where most of the character of a Vox amp is found. So I didn't like that so much.
Much better than a Tube Screamer was a Klon clone, which does a way better job of preserving the high end and the transients, so my Vox doesn't sound like it is getting truncated. The Klon clone also works nicely with my tweed Champ, as it cuts a bunch of the bottom end and makes it less boomy-dark at low volumes. I managed to make the Epiphone Dot work with the Champ at living-room volume this way, as the Dot has a mountain of low-mid boominess.
But... it still sucks a bit. The Vox loses a bit of its charm and chime with the Klon clone, as does the Champ. These are famous tube amps with glorious reputations for sounding gorgeous, so there it is: adding even good-sounding pedals is a trade-off at best.
My latest discovery in the sucking department is another surprise: my Catalinbread Belle Epoch, which famously duplicates the preamp in the old Masestro Echoplex EP3 tape echo. Apparently the EP3 preamp was so great that people used the echo unit with the echo turned off, and Catalinbread sells a version of the Belle Epoch without the delay. So, why then does it suck tone from my Champ? I compared it with the cheap EHX Holy Grail Reverb unit, which preserves the small amount of "chime" that my tweed Champ is capable of; the Belle Epoch on the other hand rounds off all those corners. Perhaps a better fit for the Vox, but on the tweed Champ, no thanks... it's a sucker.
