These are the passive tone control circuit. You can adjust audio both bass and treble without increasing the signals at output.
Treble-Bass Booster: Very like the Orange and Dallas Rangemaster boosters. Armstrong (Dan) Orange Squeezer: A plug-in-the-guitar compressor: Toner transfer package. Dallas/Dallas Arbiter. Rangemaster: A single germanium transistor treble/signal booster to overdrive a tube input. Very sweet sound Technical description of the Dallas Rangemaster. Similarly to Brian May who uses his Deacy amp with a treble booster in front, I wanted to build something similar that can be used with my germanium radios converted into guitar amps.All those amplifier circuits in radios are designed to amplify wider range of frequencies and they expect lower impedance signal at the input, so plugging the guitar straight into the amplifier may not be ideal.
We use only basic components R and C. They perform filter low or high frequency.
It is easy to build and cheap. We do not need to use any power supply. Next, its output can be increased more power with a power amplifier immediately.
Simplest tone control circuit
See in the circuit below. It is simplest tone control circuit. We can adjust bass and treble easily with rotate VR1 and VR2 to control the tone of music.
Better quality passive tone control circuit
For bass-treble tone control that has better working. It is designed by Mr Grommes. Use more R and C devices. As shown in the general standard circuit in the figure below.
The value of components in the circuit. They may be increased or decreased according to individual tastes who like the bass-treble of the music differently.
- Capacitor C1 and C2 and resistor R2 affect the bass. If the C2 value is used more. For example from 0.068uF to 0.1uF. And reduce R2 down from 1.5K to 1K will increase the bass level.
- Increasing or decreasing C3 and C4 will affect the treble signal more or less, respectively. As shown in the circuit figure below. Which is the same circuit But the level of the equipment is different.
Not only that see other passive tone control circuit below.

See the circuit that you can use it works well.
How it works
When we feed a input signal to input of the circuit. The sound signal will come in to separate in 2 the ways.
The first way will via to a low pass filter. It includes R1, C1, C2, and R2. And it has the VR1 be adjusted the low frequency ratio gain or the bass.
The second way a signal will come to a high pass frequency filter section. They include C4, R5, C5, and VR2 be adjusted the value of
high frequency or treble.
The signal from both low and high pass frequency filter flow through R3 and R4 to the output.
Then, have C3 cleans the noise signals goes out away.

The explained bass treble tone controller circuit not only facilitates the control of the bass, treble frequencies but also the mid range frequencies using its efficient 3 way tone control circuit providing an excellent custom music output as preferred by the user.
As shown in the figure below the circuit employs opamps for the processing and generates an excellent qulity sound as per the taste of the listener and enable tailored frequency music output which results in enriching even an ordinary piece of music input.
Treble Booster Pedal
The discussed bass, treble tone controller circuit thus effectively performs like a 3 band graphic equalizer circuit allowing the user with distinct 3 way control of the sound frequency.
The bass control basically allows only the lower range of the frequency, ideally between 10Hz and 300Hz, that means the user can adjust this pot to cut off all frequencies that might be within or beyond this frequency range.
The treble control can be considered just the opposite of bass, and this control allows the user to trim the input frequency within the range of 2kHz and 6kHz, which implies that the user can use this pot to tailor the frequency anywhere between this range.
Now obviously, the mid range control has the ability to provide the facility of adjusting frequencies between the above discussed 300Hz and 2kHz.
With all the 3 controls, the this simple bass treble mid range tone controller circuit becomes a full fledged 3 way graphic equalizer circuit which enables the users to adjust the 3 control as per their personal taste such that the most pleasant hearing sensation is achieved for the listener.
Hi-Fi Bass, Treble, Presence Tone Control Circuit
In this post we learn how to make a simple yet Hi-Fi super tone control circuit featuring adjustable bass, treble, and presence control circuit using potentiometers and processed using opamps.
This specific tone control features a couple of control knobs or pots which enable you to vary the presence of bass and treble within an music transmission.
Recipe and menu costing software free. A high-end integrated circuit for sound processing is employed made up of 2 operational amplifiers inside pickup.
This is the NE5532, which can be run with +/- 15V.
The 50K potentiometer on the input determines the input level or level of sensitivity of the process. The 20K preset must be initially be positioned within the middle of your pots dial.
If you find a distortion content or deformation inside the music, cut down the adjustment right up until a dedicated processing is accomplished.
Cheap Treble Booster
The 100K potentiometer sets the quantity of bass, whilst the 10K potentiometer executes exactly the same for the treble response.
Since the power supply for this simple Hi-fi bass, treble, presence tone control circuit is actually symmetrical at the port 4 of the integrated (GND marked in the image above) it ought to connect with -15V while terminal 8 (designated as Vcc) needs to go to + 15V. The body should be assembled to 0V, that the integrated will not hook up with over to the non-inverting input of the operational 2nd (port 5).
Stereo Bass Treble Control with Preamplifier Circuit
This simple, one-chip, stereo preamplifier is ideal for build-ing into an existing AF power amplifier. It is based on a recently introduced integrated circuit, the Type TCA5500 or TCASSSO from Motorola.
This double AF amplifier chip with inputs for balance, volume, and bass and treble controls forms a sound basis for a good quality preamplifier with a minimum of components.
The onset points for the bass and treble controls are defined with Ca and C4 respectively.
All (mono) potentiometers are best fitted direct onto the circuit board to make for simple mounting into a cabinet, and also to prevent hum and noise being picked up in the wiring that would otherwise be required.
The preamplifier has a current consumption of 35 mA, of which S mA is drawn by voltage regulator IC2. Zener diode D1 and power resistor R5 should be added if the positive supply voltage available in the power amplifier is more than about 30 V .
High Quality Tone Control Circuit
When constructing a superior quality preamp, the creator was confronted by the situation of creating an appropriate high quality tone control circuit stage.
Mp3 Treble Booster
Op amps including the 741 are generally utilized, however in common possess a bad slew rate, relatively higher distortion and high noise when utilized in this application.
The high quality tone control circuit revealed is dependent on an inverting op amp employing discrete transistors to get over these difficulties.
The output stage is influenced with a regular current source, biased with a green LED to offer temperature compensation.
Using the controls flat the unit supplies unity gain, therefore the stage could be turned in or out.
The layout is appropricate for inputs amongst 100 mV and IVO and supplies the best overload margin at low distortion for the precise processing of transients.
The normal screening measures towards hum needs to be performed.
