why is there a hi and lo on laney cub 10
and 15w and <1w input slot on cub 12
The Hi input basically has a little more gain than the Lo input. It is used either when you want to get more drive or if your pickups are weak.
Some tube amps have switchable wattage to allow them to be played driven/distorted at lower volumes. Its usually a wattage switch, sometimes called a Triode-Pentode switch. I haven't seen amps with separate inputs for the two...
but are they only available on tube amps??
Tube amps have a break-up zone where picking hard gives a over-driven tone and soft picking gives clean tones. The amount of volume you can achieve before break-up is called the clean headroom. As you approach your clean headroom, the clean tones will start to get slightly compressed (which I love personally).The clean headroom is affected by how hot your pickups are. If your pickups are very high output, you will have a tough time getting a really clean tone when the volume is turned up high. To overcome this, these amps have the low input where your signal is taken through some kind of a resistor or voltage step down so that your amp can operate cleaner at higher volumes.
Most SS amps don't have a break-up zone or compressed clean tones. It goes from clean to gritty/buzzy drive. This is why many SS amps don't bother putting a gain knob for the clean channel. So I don't think its all that useful but then again you can play clean at slightly higher volumes with a lo input. My Fernandes SS has Hi/Lo inputs. I have seen it on a few Marshall amps as well.
u mean that high and low is for high output and low output
What he meant was
HI mode -
Upto Volume 7 u will get Clean tone
At Volume 7 and above ur tone distorts and u get an overdriven tone
Low Mode -
Upto Volume 3 u will get Clean tone
At Volume 3 and above ur tone distorts and u get an overdriven tone
hey wylder correct me if i am wrong
Its the other way around Nikhil......In HI Mode - The breakup happens quickly and in LO mode, the breakup doesn't happen as quick.
You sure????? :O Coz i have always been thinkin the other way round....will check it tonight....
Yeah, I am sure buddy, HI mode has less headroom when compared to LO mode, LO mode is more of a clean tone for as far as you can go with the Volume, and Hi mode breaks up much quickly than LO mode.....Its for any tube guitar amp in general....not only for the Laney Cub 10.
Yup, aryasridhar is right.
As I stated earlier, I think Hi input is for putting your signal straight into the amp while Lo is for stepping it down and sending a weaker signal. So Lo would have less drive, more headroom.
In some amps there is an option for low wattage output i think the one i had seen was 10W amplifier and 2W optional knob. I dont remember exactly....I got confused in between this and Low,Hi thingy.....
