db boost pedal infront of amp

I have not tried this on a low powered amp but will a boost pedal say 20db increase the overall volume of an amp as in something like a blues jr or vox ac15 or EVH lunchbox type amps, or will the amps compression limit the volume db increase?

It will increase it until the amp like you say starts compressing. After a certain point you’ll likely only get more dirt and little volume.

Yeah, head room in pre amp circuit, type of circuit and then type of power amp circuit, inefficiency inherit to every part of the amp says you will never get a 1:1 boost from an inbound signal.

that's basically increasing the voltage of the output of the pickups 10 fold.

20dB of volume is an incredible amount of volume increase -almost 4 times in perceived loudness.

Not happening

Doesn't mean it won't increase it dramatically though. even 2x is significant -unless your speakers blow
 
Re: db boost pedal infront of amp

If your goal in using a boost pedal is to get more volume you are going to be very disappointed. Yes, the amp will get louder, but that is not the function of a boost pedal. The boost pedal is used to boost your line output from the guitar and hit your preamp harder. With this, you will see more gain, and there will be some colorization of the tone and shift in, eq. This is a very desirable effect for a lot of guitar players including myself. However, if you are just looking for an increase in volume get a bigger amp. To answer your question about using a boost with a lower wattage amp. The right boost will make them sing and give you dynamics you never thought were possible playing the guitar.

I never play (live/studio) without a boost inline sometimes I have two.

don't forget it's other critical role -to buffer before and or recover your signal after these savages put a half dozen true bypass pedals in a row.

I run 2, both always on -one at the stage front before the long haul to the amp and one after the modulation pedals that sit before the amp.

The same here I have usually a Rangemaster clone at the top of the chain and my Morley which is a bit more transparent at the bottom.
 
Re: db boost pedal infront of amp

I use the Pickup Booster pedal for a slight volume boost. I use it into a clean tube amp (6v6s) that isn't up loud enough to distort, and it adds volume and some compression, but I'd still have to hit the guitar really hard to get it to distort.
 
Re: db boost pedal infront of amp

Hey OP, forgot one other factor, What you want to do all depends on how much headroom you are utilizing now without.

It you are running something really hot like a Duncan invader, a boost pedal will only provide a marginal increase before you max the preamp headroom out

If you are running something low output like a PAF or a P90, then you'd have lots of available headroom to use a boost to maximize the gain presented to the preamp circuit thus seeing a significant loudness increase from the amp.

Even so, your going to lose the battle eventually -a bigger amp is inevitable.

Are you running passives or actives into this unit?

Fun fact: Tom Morello uses an old DOD EQ pedal (FX 40B) to push 18db into his Marshall.
 
Re: db boost pedal infront of amp

Passives, like the Alnico II Pro, Custom 5, Custom Custom, Jazz, 59, and 59/Custom Hybrid.

So you are basically using an ultra transparent buffer and boost -almost like a light active pickup preamp outside your guitar?
 
Re: db boost pedal infront of amp

Almost like a pickup.... booster.

I didn't do anything important -unless getting pizza and setting up monitor mixes and moving mic stands is important.

Ah damn -I totally forgot that it was called an SD "Pickup Booster" hahahahaha . I was thinking it was a Seymour Duncan "Boost pedal"..

Ok... time for bed!!!!
 
Re: db boost pedal infront of amp

I find boost pedals add a little bit of perceived extra volume, but not a huge amount. I also find that they can make the amp break up a little earlier, and they also change the pick attack and touch sensitivity a little, which can be good or bad depending on the amp.

Remember these pedals are just pushing the preamp harder, what happens after that is all the amp. So an amp with a low gain preamp will get a bit louder and a bit dirty with a dB booster pedal. A high gain amp likely won't change too much, depending on your settings of course..

He's also not the brightest musician ever (sarcastic understatement)...for all its reputation, there's only so much Harvard can do

Yeah. I don't set it to color the tone at all. I back it off so the sound is the same, just louder.
