Hey all,

Is the perceived volume attained on the Hot Rod Deluxe pretty much average for most 40 watt tube amps? I don't have a lot of experience with tube amps, so when I hear of people using 40 watt tube amps for "bedroom practice" I'm somewhat shocked.

(Personally, I find the HRD gets loud... quickly with the volume set low... :) )
Your perceptions are quite right.40 watts is really loud.For at home practice I usually use my deluxe reverb and thats pretty loud,but I live alone , so volume isnt a problem.

The HRDlx is no louder than any other 40 watter. It just gets there faster because it uses a linear taper pot so by the time you hit 3 or 4 on the dial, it's almost running flat out. It's all a marketing ploy. Hot Rod, get it?

I use a Vibro-Champ XD for playing at home and even at 5 watts it is really loud in the house!! (Actually sounds like a MUCH bigger amp in the house and is perfect for that purpose).


Cheers,

Snowy

Maybe the question I should've asked is if there is a 40 watt Fender amplifier that has to be turned up more before you are running flat out.

For example, I recently played a Peavey Valveking 112 (50 watts) that didn't seem to get as loud so quickly.

Also, I'd be interested in checking out the Deluxe VM and Super Sonic 112 if they had more "volume restraint".... :)
Like Supro said , one of the features of the HotRod is that it gets loud quickly.This is due to the volume pot.My Bassman amp doesnt even make a sound until almost 3 on the volume knob.Many people use a volume box in the effects loop to rectify this problem, others use the volume knob on their guitar.

My Hot Rod Deluxe was the ONLY amp that ever did that. That was reason #4 out of many that I dumped the thing. :D

Another thing to consider: An amp with a more efficient speaker will probably sound louder than another amp with the same wattage but a less efficient speaker.

We're talking a HRDlx here. There isn't an efficient anything in that amp. :D

Loudness is not measured in watts, but in db's spl (decibels sound pressure level). Depending on how much of the wattage is dissipated (burned off) in heat (rated as efficiency) determines how loud (or not) an amplifier is, NOT how many watts it has!! In other words you can have two different 40 watt amplifiers, and one can be 2-4-or even 10 times louder than the other one, depending on how much more efficient one amp is compared to the other. I hope I've answered your question sufficiently.


It will still be 40 watts of power. That doesn't change. It won't be 2-10 times louder. It may be perceived that way, but 40 watts is still 40 watts. It's all in the efficiency, number of speakers and the amount of air that is being moved. A stock DRRI or even my 20 watt Egnater Rebel cuts way better than my HRDlx ever did and I don't really need to crank it. It's just a more efficient setup.

First off, Lighten up!!!! I'm not a 15 year old kid. I'm up for any discussion but don't talk to me like I'm an idiot. Second you're comparing an 65 watt solid state amp to a tube amp. You are comparing a current driven device to a voltage driven device. You don't HAVE 40 watts going into an amp circuit, The 40 watts is being CREATED by the amps circuit and transformers. You can only produce so much power from each power tube. 6L6 power tubes are I believe 18 watts each. We are talking watts not Db's and SPL's. That will change with the efficiency of the speaker.

The Hot Rod series amps use a LINEAR TAPER POT to make the amp SEEM louder than it really is when in fact it's running almost full tilt before it hits 5 on the dial.

I NEVER disputed that loudness was measured in decibels and sound pressure levels. The OP asked why some 40 watt amps are louder than others. The amps POWER is measured in WATTS. Loudness you have RMS, Peak Music Power etc. The amp itself isn't rated by decibels or spl, but the speaker is. If you can't understand the difference between a solid state amp and a tube amp then I give up. Nowhere in the HRDlx specs does Fender mention decibels.

I played with musicians who used Deluxe Reverbs at 22 watts through 4x12 cabinets that blew my HRDlx off the stage. Why? Because more air is being moved and the result is a PERCIEVED power increase. The 22 watts is being used more efficiently. 40 watts is still 40 watts the power of the amp doesn't change, the EFFICIENCY of the output will change depending on the EFFICIENCY of the speaker and how many you use. The power does not change. You are merely utilizing the full potential of the amp. That is the only reason one 40 watt amp may sound louder than another 40 watt amp. To compare SS and tube amps is just apples and oranges. Again a 40 watt SS amp is just less efficient than a 40 watt tube amp by design. Current vs voltage.
I'm done with this one. Rolling Eyes
