Permalink Crate PowerBlock vs random amp...

New Topic
Page 1 of 1

Hi all!

My 'sound' up to now when rehearsing and gigging is defined by my strat and my pedals. I haven't got a decent amp yet so I plug into whatever amp I find there.

How would the PowerBlock compare to a random transistor Marshall or a Hot Rod Deluxe? I'm considering getting one as my main amp. Is it bassman-like or blackface-like? Does it sound like a ss rectifier amp or does it sag? Mids scooped or normal?

These are great little amps. I have been planning on picking one up as a touring backup for some time now. However, comparing them to and Fender Tube amp is futile. They are just not the same. They do have a great clean tone though. Mostly, though, your sound will still be defined by what pedals you are using.

Power Blocks are clean transistor sound: sort of like a Roland keyboard amp, or an PA system. Takes the input signal and amplifies it with very little coloring of the tone. There is a bit of drive to a Power Block if you push the input volume. The tone section does boost or cut highs, mids and bass...the bass frequencies seem most pronounced.

A powerblock is my main gigging amp right now ( until my silvertone is out of the shop ) and I love it.

Noah is dead on. The clean is good and you will have to use pedals. However i discovered that of you crank the gain all the way you get a very marshally/plexi-like growl. Plus it fits in my gear bag!

Psycho surfabilly!

i have a friend with one, its really great thing to keep in your trunk just in case your tube amp craps out

I usually use a Silvertone 1485 but I've been using a Powerblock with an old 15" Pyledriver lately for convience purposes. It's good for live situations and I don't mind using a solid state amp for live gigs but deff not recording, too shrill and hard sounding for me unless I'm running several amps and blending. Go ahead, get the Crate. I crank the level all the way, use the gain as my main, high at about 3:00, mid around 12:00 and low around 9:00, sounds good with my 15, don't know about a 12.

A lot of us like the Powerblock. Mostly for a backup. I used mine on a gig and liked it. More discussion here:

Thanks for the info guys! I've read the other threads that discuss the Powerblock, I just wanted some more details.

When you say I'm going to need pedals you're talking about drive/distortion, right?

Reverb...You can get some drive from the head, but you will probably want an overdrive pedal and/or distortion pedal.

I bought a Powerblock yesterday! Smile

I listened to it through a 1x12 and a 2x12 cab and I A/B-ed it with a JTM45 (made with old stock materials)

Impressions
It sounds nice. I like the clarity and the definition of the notes. It does sound sterile but I think I am hearing what my guitar sounds like with no coloring whatsoever. Ofcourse it's colored by the speaker but I'm feeling it's the most neutral sound I've gotten. The JTM45 on 1-2/10 was much better, sounding full and spacious and alive, but this is to be expected when comparing a 130euro SS amp with a 1800euro handwired (old stock) tube amp.

I tried my Hardwire RV-7 reverb and a couple of overdrive pedals with it and I think the sterility remains. I'll have a better versed opinion after I've played it for some time.

Questions
What is a 'speaker cable', how does it differ form the usual 1/4" instrument cable and what happens if use the usual 1/4" instead of a 'speaker cable' to connect my Powerblock to a cab? (or any other amp head to a cab)

I found the Powerblock not loud. With level maxed, I needed the gain at 7/10 to get a loud enough sound for a miced gig through the 2x12. The 1x12 was even less loud. Is there any case my PB is broken?

What's with the multiple outputs? I know I shouldn't plug an amp into speakers with less impendance that the amp's designed for. I also know that amps shouldn't work without a load. PB has an 150W @ 8Ω MIN mono outpout and two (left-right) 75W @ 4Ω MIN outputs. If I have a 4Ω cab can I use only one mono output? Will it feed power to both L/R resulting in failure of the other mono output?

I know how I should match amp/cab imepdances but what about matching wattage? How is it fed and distributed to multiple speakers and what are the tolerances/acceptable deviations?

Has anyone tried the xlr line-out to a console? What do you think of the built-in speaker simulation, quality-wise?

If the amp ends up sounding too sterile for you, I suggest picking up the Boss FDR-1 or FBM-1 pedals. That should do a decent job of giving you a fender amp tone, while using the power block as you power amp.

Instrument cable vs. Speaker cable from Fender.com.

If you use an instrument cable as a speaker cable, you're probably OK at low signal levels. At high signal levels, though, trouble brews—all that amp power attempts to flow through the instrument cable's too-small conductor. The unhappy result is that a lot of amp power is converted to heat and never even reaches the speakers. You get reduced speaker output, some probable distortion and, in extreme situations, heat-induced cable or cable connector failure. And you definitely don't want your amp overheating.

One thing to remember with the Power Block is it's only 75 watts per channel. To get the 150w you need 2 cabs. That may be the volume issue you're having.

How many guitars are enough?

Just one more...

Mono is 150 watts, stereo is 75 watts per channel. 2 cabs is not necessary to get 150 watts.

Ah, my bad. It's been a few years since I used one.

I was in a band with 2 other guitarist that used them. Almost bought one, but never got around to it. They are killer amps for anyone that uses a lot of effects or a processor. It's a good backup too.
