For those about to conserve CPU in boosts and drives

Just a little reminder of things probably discussed ad nauseam, but might be appreciated by some.

The Bosom Boost and the Tube Drive (all of them, even the 5-knob) are several clicks less CPU than any other drives. A difference of 4 to 5 %. Both have ample eq to mimic much of the other drives. FET boost and preamp are lean too.

A Filter, Graphic or Parametric EQ can also do a great bit of boosting at even less CPU than drives.

Of course, using the boost within the amp block is ultralean since this is on the other CPU and doesn't add to CPU% count at all (I think), it's just less programmable and accessible. I prefer the drive block for those reasons.

How is it ‘less programmable and accessible’? Genuinely curious, because I tend to use the preamp boost in the amp block, but haven’t encountered any issues with programmability or accessibility.

Thanks!

The Boost in the Amp block is only the EQ of the Drive block with a level.

You don't get a Drive control, any tone shaping controls, etc.
 
The Bosom sounds great and yes it’s cheap on the cpu. I prefer other drives like the Klon, Paradigm, and the Photon, the higher cpu models. The cpu on the FM3 is limited but it’s almost a non issue for me since I make multiple copies of my main amp/cab combos featuring different sets of effects. Preset switching is gapless and I sometimes switch presets mid song. It helps to have more switches and less tap dancing but it works. I just can’t squeeze it all into one preset.

Good tip though especially for newer users that may not be aware that not all drives use the same amount of juice. This is true for a lot of the blocks not just drives. I use the Plex a lot and I haven’t heard everything it can do because of the constraints.

The Boost in the amp block only has a type selection and a level parameter, it has drive of the specifide pedal at 0 and no tone setting. Very useful but not as flexibly programmable as a full Drive block since no drive, tone knob or EQ.

It's not a separate block so it's less accessible. It needs some more programming to make it switchable. I actually never got into what it needs to do that, I think attaching a control switch to the boost and then pointing an FC place to the Control Switch, therefore it is more work to program. Not much and not difficult by any stretch, just a little more than my lazyness has allowed and needs have necessitated up to now. But should you have this need to run really lean, it's an option.

AFAIK, the Input Boost does not apply the EQ settings from the drive block, should you take above to mean that. My slightly autistic mind went there for a second. It's the EQ of the modelled pedal with tone set somewhere Cliff liked, I presume, but the tone settings in the drive block do not transfer to the input boost in the amp block. Of course Unix-guy knows more than I do.
